1. INTRODUCTION
Over the last four decades, anthropometric history has studied the changes in human welfare based on height and the construction of health indices, analysing the complex relationships between economic growth and the biological welfare of communities in the last three centuries (Komlos Reference Komlos2009; Steckel Reference Steckel2009; Fogel et al. Reference Fogel, Floud, Harris and Hong2011). Spanish historiography has made significant progress in recent years (Martínez-Carrión Reference Martínez-Carrión2002a, Reference Martínez-Carrión2014; Martínez-Carrión and Moreno-Lázaro Reference Martínez-Carrión and Moreno-Lázaro2007; María-Dolores and Martínez-Carrión Reference María-Dolores and Martínez-Carrión2011; Spijker et al. Reference Spijker, Cámara and Blanes2012; Ayuda and Puche Reference Ayuda and Puche2014; Martínez-Carrión 2016; Puche and Cañabate-Cabezuelos 2016; Pérez-Castroviejo 2016). Although significant achievements have been made, a more in-depth statistical study of welfare is required, particularly with respect to biological inequality in the Spanish rural community (in 1900 the Spanish agricultural sector still employed 60.7 per cent of the active population).
The pioneer study in this field referred to the region of Murcia (Martínez-Carrión Reference Martínez-Carrión1986), and was followed by others focussed on other geographical regions of Spain, such as rural Catalonia, eastern Andalusia, Castile-Leon and Madrid (Cámara Reference Cámara2009; Garcia-Montero Reference Garcia-Montero2009; Hernández and Moreno-Lázaro Reference Hernández and Moreno-Lázaro2009; Moreno-Lázaro and Martínez-Carrión Reference Moreno-Lázaro and Martínez-Carrión2009; Ramon-Muñoz Reference Ramon-Muñoz2009) and on Spain as a whole (Beltrán Reference Beltrán2015). All of them reveal that the liberal reforms and the beginnings of agricultural capitalism in the mid-19th century did not lead to the improvement of the biological living conditions of the Spanish rural population. The privatisation of communal lands in some regions (e.g.in rural eastern Andalusia) did not have positive effects, increasing inequality within rural communities.
The diversity characterising the Spanish agricultural sector at the end of the 19th century, due to the land tenure system, the crop and livestock farming systems, the techniques used, the levels of capitalisation, the unequal presence of irrigation, the yields obtained and the type of land or the climatic conditions, indicate that a more in-depth study of the relationships between biological welfare and agricultural growth in rural Spain is required. This article, which analyses the height of males in irrigation areas in rural Valencia between the mid-19th century and the mid-20th century, represents a contribution in this direction.
In this context, this study has a double objective: first it evaluates the impact of agricultural growth on the biological standard of living experienced in the irrigated areas of Valencia between the mid-19th century and the mid-20th century; and second, it calculates how this process affected the inequality in the biological welfare of the population engaged in agriculture, distinguishing between farmers and farm workers.
The new institutional framework that emerged from liberalism and the boost of the international markets gave rise to the growth of intensive crop farming in the irrigated areas of Spain. Therefore, it is necessary to analyse the impact of this growth model based on intensive agriculture and exports on biological welfare and health, and the extent of the socio-nutritional inequalities within the rural communities. Until well into the 20th century, land ownership was generally considered as the principle expression of social inequality within rural communities (Garrabou et al. Reference Garrabou, Planas, Saguer and Vicedo2014), and in the Valencian agricultural sector small and medium-sized farms predominated over large propertiesFootnote 1 . In this study we analyse the average height of the rural conscripts in accordance with their access to land ownership. We have divided the individuals of the sample into two social classes in accordance with the social classification of the primary sector in HISCLASSFootnote 2 ; farmers and farm workers. Although the HISCLASS classification divides primary sector workers into three groups (farmers, lower-skilled farm workers and unskilled farm workers), we have joined the latter two into one group which we have called farm workers, as our sources do not enable us to make this distinction.
The principal sources of data for this study are the height data corresponding to 14,199 conscripts engaged in agricultural activities (of which 10,493 were farmers, and 3,706 were farm workers), who were measured in five municipalities of the eastern part of Valencia where irrigated farming was developed, at least after the mid-19th century. This rural sample has been obtained from the 48,841 conscripts of these municipalities during the period of study. A weakness of this rural sample is the limited number of observations for the 1860s and 1870s as there was less information available regarding the profession of the conscripts compared with the subsequent decades. Therefore, in this article we have used the overall sample of 48,841 conscripts (total population of young men) to analyse the evolution of the average height in the irrigated area of Valencia and the sample of farmers and farm workers to analyse the biological inequality in accordance with their access to land ownership. The results reveal that there was a growing trend in evolution of height in these rural areas over the long term. In contrast to the observations of other rural areas of the Spanish Mediterranean (Martínez-Carrión and Pérez Castejón Reference Martínez-Carrión and Pérez-Castejón2002; Ramón-Muñoz Reference Ramon-Muñoz2009), our results suggest that in the irrigated area of Valencia the beginning of the agricultural changes and the intensification of production in the mid-19th century did lead to an improvement in the biological welfare of the populations. Our results also reveal nutritional inequalities between the rural groups; the landowners always had higher levels than landless farm workers. It can be deduced that access to landownership became a determining factor of the socioeconomic and biological differences in the traditional agricultural societies. These biological differences have also been documented in other Spanish rural areas, such as south-east Spain (Martínez-Carrión and Pérez-Castejón Reference Martínez-Carrión and Pérez-Castejón2002).
Throughout the second half of the 19th century and the first-third of the 20th century, as in other rural Mediterranean parts of Spain, the production systems in Valencia’s agricultural sector underwent a remarkable modernisation and intensification process. This occurred in parallel with the progressive integration of the region’s agricultural sector into the international economy within the context of the first globalisation process, due particularly to the growing export orientation of the economy. The region of Valencia, like other eastern and southern regions of Spain, gained comparative advantages by specialising in certain crops, such as citric fruits, rice, vegetables, olives and grapes. This enabled it to extend its exporting capacity and food supply to the national and international markets. This agro-export model was based, in turn, on: the widespread use of irrigation, the early incorporation of inorganic fertilisers, the adoption of crops that generated high physical and monetary yieldsFootnote 3 and the predominance of skilled manual labour in agricultural tasks that were difficult to mechanise. Furthermore, the agri-food sector experienced a significant diversification and modernisation process and a considerable increase in its production capacity (Garrabou Reference Garrabou1985; Piqueras Reference Piqueras1985; Mateu and Calatayud Reference Mateu and Calatayud1996; Calatayud Reference Calatayud2001; Calatayud and Millán Reference Calatayud and Millán2010).
The study is structured into five parts. After this introduction, the second section describes the principle changes in production experienced by the irrigated area of Valencia between 1850 and 1930, whereby the region’s agricultural sector became integrated into the international markets and the irrigated area oriented a good part of its production towards the market. The third part describes the sources and the sample used in the study together with the methodology applied. In the fourth section, the results are presented. Furthermore, the impact that the process of agricultural growth had on the biological welfare of population in the irrigated area of Valencia is analysed. In addition, biological inequality in accordance with access to land ownership is also addressed. Several models have been estimated for both of these aspects. The final conclusions are drawn in the fifth and closing part of the study.
2. THE IRRIGATED AREA OF VALENCIA, 1850-1930
Throughout the 19th century, Spanish agriculture underwent a growth process that was driven both by higher demand due to an expanding domestic market in which some products (such as wheat) received considerable protection, and booming external demand for products such as wine, oil and vegetables from countries in western Europe (Garrabou and Sanz Reference Garrabou and Sanz1985; Pinilla Reference Pinilla1995; Gallego and Pinilla Reference Gallego and Pinilla1996). This expansion, however, did not give rise to any significant technological changes because the aridity of most of the Peninsula restricted the adoption of the innovations arising from the Atlantic agricultural revolution.
The agricultural crisis at the end of the century and a new technological supply from the United States gave rise to greater changes in the first-third of the 20th century, with a significant increase in labour productivity (Bringas Reference Bringas2000; Gallego Reference Gallego2001). However, despite this undeniable improvement, in 1935, it was still lower than that of the majority of western European countries (O’Brien and Prados Reference O’Brien and Prados de la Escosura1992, pp. 530-531). Spanish agriculture required a large workforce, not because of the farmers’ resistance to change, but due to the low level of development of industrial activities which gave the sector significant weight in the economy (Silvestre Reference Silvestre2005). The agricultural sector was characterised by the high price of capital and the low price of labour, which hindered a more profound technological change (Clar and Pinilla Reference Clar and Pinilla2009).
Within this context, the agricultural sector of the Mediterranean coastal area, particularly in the province of Valencia, had specialised in vegetables which incurred relatively low comparative costs. The specialised agriculture of the Spanish Mediterranean area became integrated into international markets and experienced significant development (Garrabou Reference Garrabou1985, Pujol et al. Reference Pujol, González, Molina, Fernández Prieto, Gallego and Garrabou2001; Pinilla and Ayuda Reference Pinilla and Ayuda2009, Reference Pinilla and Ayuda2010; Ramon-Muñoz Reference Ramon-Muñoz2013). The irrigated area of Valencia developed considerably at the end of the 19th century and during the first-third of the 20th century and Spain gained significant weight in international markets in terms of these products (Garrabou Reference Garrabou1985; Piqueras Reference Piqueras1985, Reference Piqueras1999; Garrabou and Pujol Reference Garrabou and Pujol1988; Calatayud Reference Calatayud2001; Pinilla and Ayuda Reference Pinilla and Ayuda2009; Calatayud and Millán Reference Calatayud and Millán2010).
From the 1850s and after the culmination of the crisis of trade specialisations which began in the 18th century (barrilla plant, silk and later, hemp), the Valencian agricultural sector began to cultivate a new wave of crops for domestic and international markets. Although the expansion of vine-growing activities was mainly concentrated in rainfed areas, in the long term, agricultural growth in the region of Valencia was based on irrigated farming. In 1922, this intensive farming represented a quarter of the cultivated area, but if we examine the value of production, in 1931, fruit and vegetables represented 67 per cent (Calatayud Reference Calatayud2001, p. 166; Calatayud and Millán Reference Calatayud and Millán2010, p. 213). The irrigated area of Valencia was very diverse which gave it numerous production options. This means that we must consider the different specialisations, each with their own specific characteristics, as the studies carried out indicate that from the end of the 19th century, there was a trend that ran in parallel with the concentration of ownership and the consolidation of family ownership. The significant development of the irrigated area of Valencia was not only based on the new agricultural bourgeois class (Calatayud et al. Reference Calatayud, Millán and Cruz1992), but also on small landowners and tenants. The small farms were as profitable or even more so than the medium-sized and large farms (Calatayud Reference Calatayud1989a). Far from a cereal monoculture, rice, oranges and a variety of vegetables with a more dynamic demand contributed to the strong boom experienced in the irrigated areas in the second-half of the 19th century and the first-third of the 20th century (Garrabou Reference Garrabou1985; Piqueras Reference Piqueras1985, Reference Piqueras1999; Calatayud Reference Calatayud1989b, Reference Calatayud2001; Garrido Reference Garrido1999, Reference Garrido2004; Palafox Reference Palafox2001; Pinilla and Ayuda Reference Pinilla and Ayuda2008; Calatayud and Millán Reference Calatayud and Millán2010). Consequently, the region of Valencia increased its exports of horticultural products. Figure 1 shows that this growth was spectacular, multiplying by ~16 between 1861 and 1913. During the First World War, however, exports experienced a significant decline, but recovered again in the 1920s (Piqueras Reference Piqueras1985, Reference Piqueras1999).

The amounts exported have been drawn from Piqueras (Reference Piqueras1985, pp. 229-230) and the prices of the different products from Gallego and Pinilla (Reference Gallego and Pinilla1996).
As a result of this commercial dynamism, Valencian exports represented a significant percentage of Spain’s total exports of Mediterranean horticultural products. The case of oranges, a crop almost exclusively grown in Valencia’s coastal areas, was spectacular, but this was not an isolated case (Calatayud Reference Calatayud1989a, Reference Calatayud1989b; Garrido Reference Garrido1999). In addition to oranges, rice and horticultural products were also significant. The latter, although covering only 10 per cent of the cultivated land, had an important qualitative weight. In around 1930, vegetable crops formed a highly significant part of Valencia’s agricultural sector and in many aspects were relevant for the economy: the income generated (including currency for exports), the labour employed and the ties with other associated activities. In addition, the production of vegetables consolidated one of the most characteristic areas of rural Valencia, la huerta (orchard)Footnote 4 (Calatayud Reference Calatayud2001; Calatayud and Millán Reference Calatayud and Millán2010).
3. DATA AND METHODOLOGY
In order to address the objectives described, this study analyses the height data of 14,199 conscripts engaged in agricultural activities, corresponding to the cohorts born between 1859 and 1939. These were the generations which carried out their military service between 1879 and 1960. The height data and other variables of interest (level of education, place of birth, appeals in order to be declared exempt from military service, and, most of all, access to land ownership) are drawn from the local military recruitment series of five municipalities in Valencia which, at least from the mid-19th century, were engaged in the intensive crop cultivation characteristic of irrigated farming (Figure 2). Several criteria have been considered in the selection of the municipalities: the characterisation of the agricultural growth model based on its product specialisation; the geographical location and restricting environmental conditions and the availability of long-term local military recruitment series. Based on these criteria, the five towns selected were: Villarreal (province of Castellón), Alzira, Sueca, Gandía (province of Valencia) and Pego (province of Alicante).
Municipalities analysed Notes: Municipalities of the sample (district, province and principal production specialisation): (1) Villarreal (Plana Baja, Castellón; oranges); (2) Alzira (Ribera Alta, Valencia; oranges and vegetables); (3) Sueca (Ribera Baja, Valencia; rice and vegetables); (4) Gandía (La Safor, Valencia; oranges, raisins and vegetables); and (5) Pego (Marina Baja, Alicante; rice, oranges and raisins).

Villarreal is located in the region of La Plana Baja. It developed a specialisation in oranges cultivated for export very early on (from the 1820s). The main players in the expansion of citric fruit cultivation, which intensified from the 1870s, were the small landowners who planted orange trees in their grovesFootnote 5 (Garrido Reference Garrido1999, Reference Garrido2004). In Alzira (Ribera Alta), however, the growth of orange cultivation was due to the landlords, who, in the mid-19th century, focussed on marginal carob and olive grove areas, while the orchards were used for crops for self-consumption and to be sold on the market (vegetables, tubers and bulbs). The new crop incorporated into the intensive agriculture of the groves in Júcar stimulated a high demand for paid labour which was covered partly by families who had small plots of land (Calatayud Reference Calatayud1989b; Garrido Reference Garrido1999; Calatayud and Millán Reference Calatayud and Millán2010). The expansion of orange crops across non-irrigated areas which were watered with groundwaters, extended to other municipalities of Valencia, such as Gandía (La Safor) and Pego (Marina Alta). In both towns, the importance of irrigation reinforced the leading role played by small farms with their intense specialisation in vegetable cultivation (Calatayud and Millán Reference Calatayud and Millán2010). The stimulus from urban and international markets was decisive for the growth of irrigated crops. The final municipality selected is Sueca, which is intensely specialised in rice and which has highly defined environmental characteristics. Rice was the intensive crop with the most weight in the irrigated area of Valencia for the whole of the 19th century. This crop was able to supply the annual peasant self-consumption and also provide a surplus to be sold on the market. It had a high output per unit area and experienced a growth phase until the 1870sFootnote 6 . After the difficulties of the 1880s, and despite tariff protection from 1891, rice underwent a technical improvement process which translated into a recovery of profitability, an increase in yields (due to the use of chemical fertilisers and progress made in seed selection) and a growth in exports (Garrabou Reference Garrabou1985; Piqueras Reference Piqueras1985; Calzado Reference Calzado1995; Calatayud Reference Calatayud2001). With greater or lesser intensity, in the five municipalities selected, agroindustrial activities were developed from the end of the 19th century (Piqueras Reference Piqueras1999; Calatayud Reference Calatayud2001). In summary, in our case the five municipalities selected represent different areas of rural Valencia which adapted their production structure, within a context of agricultural specialisation, to external markets.
Although in 1900 all of the municipalities analysed—except for Pego—had populations of >10,000 inhabitants, they were not urbanised until the mid-20th century. They were «agro-towns» as the majority of their inhabitants were employed in the agricultural sector (Martínez-Carrión and Moreno-Lázaro Reference Martínez-Carrión and Moreno-Lázaro2007; Ayuda and Puche Reference Ayuda and Puche2014).
To analyse the biological inequality in accordance with access to property ownership, we have used the anthropometric rural sample of 14,199 conscripts who declared that they were employed in production activities related to agriculture and livestock farming (Table 1). The number of conscripts who declared themselves to be land-owning farmersFootnote 7 is 10,493 (73.9 per cent of the sample), of whom 9,503 (90.6 per cent) were born and measured in the same municipality as those making up the sampleFootnote 8 . On the other hand, the number of conscripts who declared themselves to be landless farm workersFootnote 9 is 3,706 (the remaining 26.1 per cent of the sample), of whom 3,131 (84.5 per cent) were born and measured in the same municipality as those who made up the sample (Table 1). The possibility that this rural sample is biased in some way cannot be ruled out, as we do not have information about the individuals who may have emigrated before being measured in the municipalities analysed in this study. However, it can be confirmed that for our case this bias would not be highly relevant, because as the intensive agriculture in the region of Valencia offered greater job opportunities and required more labour and capital, there was a low incidence of emigration among the population of the irrigated area of ValenciaFootnote 10 . This was related to the development of small and medium-sized farms which were more prosperous in terms of employment and wealth in contrast to the poverty of the farm workers of other Spanish agricultural regions (Martínez-Carrión Reference Martínez-Carrión2002b, p. 30). The breakout of the First World War gave rise to an increase in migrations from the irrigated area of Valencia which was much affected by the international situation and the fall in its main agricultural exports (Nicolau Reference Nicolau2005, p. 92)Footnote 11 .
RURAL SAMPLE CHARACTERISTICS, BIRTH COHORTS OF 1859-1939
Note: The average heights have been calculated for the sample of the conscripts engaged in agricultural activities.

Our rural sample has two advantages: first, the data enable us to evaluate the role that access to land ownership had on height and on the biological welfare of the rural populations of the irrigated area of Valencia between the mid-19th century and the first-third of the 20th century; and second, working with data of an almost homogeneous population implies that our results are probably not affected by cultural or genetic factors which have been pointed out in other studies (Blum Reference Blum2013).
Although the data corresponding to the Spanish conscripts do not have any truncation problems due to the requirement of a minimum height as in the case of other national armies in the 19th century (Komlos Reference Komlos2004), they do suffer from problems shared by other countries. The most important refers to the successive changes in the age of recruitment which occurred in Spain between 1856 and 1907. From the implementation of «universal» conscription, between 1856 and 1907, the legal age for military service was modified four times: 1856, 20 years of age; 1885, 19 years; 1901, 20 years again; and 1907, 21 years. In order to resolve this problem, we have standardised the heights of the conscripts aged 19 and 20 to the age of 21Footnote 12 , following the methodology applied by Ramon-Muñoz (Reference Ramon-Muñoz2009). According to our calculations, we have increased the height of the conscripts measured at 19 years of age by 1.5 cm and those measured at the age of 20 by 0.7 cm (Ayuda and Puche Reference Ayuda and Puche2014)Footnote 13 . Subsequently, and to verify the quality of the data, we have constructed two histogramsFootnote 14 which show the frequency distributions of the heights of the conscripts engaged in agricultural activities and measured between 1879 and 1920 (cohorts of the second-half of the 19th century) and between 1921 and 1960 (cohorts of the first-third of the 20th century). In general terms, the histograms show a normal distribution (Figures A1 and A2 of the Appendix).
The anthropometric analysis is divided into two parts. First, the evolution of the biological welfare in the irrigated areas of Valencia has been examined based on the trend in the average height of the conscripts recruited in the five municipalities of the sample and after focussing on the conscripts who were land-owning farmers and landless farm labourers among the birth cohorts of 1859 and 1939. Second, several models have been estimated with the aim of establishing whether being a landowner enabled farmers to exercise control over agricultural production and, in general, whether having a higher level of economic resources influenced physical growth and final height. As control variables we have used the towns where they were measured, the decade of birth, the physical appeals and social type (e.g. economic poverty, family situation or being an orphan) presented by the conscripts to appeal for exemption from military service, the level of literacy and the place of birth. Furthermore, and in order to study the relationship between height and access to land in greater depth, as well as estimating a model for the whole of the period under study, we have estimated another two models for two different sub-periods: the birth cohorts of 1859-99 (6,801 conscripts, 47.9 per cent of the sample) and the birth cohorts between 1900 and 1939 (7,398 conscripts, the remaining 52.1 per cent of the sample). This chronological division is determined by the agricultural crisis at the turn of the century, which constituted a point of inflection in the evolution of the Spanish agricultural sector, and the evolution of Valencian agricultural exports. This crisis, however, did not have a highly significant impact on the agriculture of the Valencian region. The fall in production was much less serious than that of other regions and the structure of crops did not change radically. With respect to agricultural exports, considering that they experienced moderate growth until the beginning of the 1890s, we have decided to integrate the 1890s into the first sub-period. The beginning of the first of these periods was characterised by the consolidation of new property rights, the emergence of a renewed agricultural elite class made up of the new purchasers of rural assets in the 19th century and the boom in intensive crops. The second stage was characterised by the definitive advance of specialised irrigated crops and the maximum expansion of commercial agriculture (Calatayud Reference Calatayud2001).
4. RESULTS AND DISCUSSION
4.1. Evolution of Height in the Irrigated Area of Valencia
Figure 3 shows the average heights of all the conscripts in the five municipalities making up the sample of the irrigated area of Valencia corresponding to the birth cohorts of the 1860s and 1930s, and the evolution of the coefficient of variation of height (CV)Footnote 15 , originally suggested by Baten (Reference Baten2000b) and used in other studies as a indicator of economic inequality (Blum Reference Blum2013; Ayuda and Puche Reference Ayuda and Puche2014). The height data reveal, on the one hand, a secular growth trend of biological welfare in the long run, and on the other, the existence of some downturns that altered the growth rhythm of this trend, e.g. during the decade of the 1890s.

In the long term, the average height of the conscripts in the irrigated area of Valencia increased by 3 cm, if we take the averages of the birth cohorts of the 1860s and 1930s as a reference, with average height estimates of 163.8 and 166.8 cm, respectively.
The CV suggests that the height inequalities were acute in the mid-19th century, then they diminished at the end of the century and increased slightly with the birth cohorts of the 1900s and 1930s—the military recruits of the initial years of the Franco regime (Figure 3). In general, the evolution of the average height and the CV for the irrigated area of Valencia was very similar in the analysis of height in accordance with access to land ownership (Figure 4), except in the first two decades, may be due to the bias mentioned in the introduction.

Spanish anthropometric historiography has revealed that the beginning of Spain’s modern economic growth in the mid-19th century did not give rise to an improvement in the living and health conditions of the urban and rural communities (Martínez-Carrión and Pérez-Castejón Reference Martínez-Carrión and Pérez-Castejón2002; Martínez-Carrión and Moreno-Lázaro Reference Martínez-Carrión and Moreno-Lázaro2007; Ramon-Muñoz Reference Ramon-Muñoz2009). The results obtained in this study, on the other hand, reveal an improvement in biological welfare in the irrigated area of Valencia in the middle decades of that century. Of the cohorts of the decades of 1860 and 1880, the average height of the population of the irrigated area of Valencia increased by 1 cm coinciding with the extension of intensive farming and the intensification of production for the market, and all of this in spite of the extension of child labour and the increase in morbidity and mortality rates.
Studies carried out on the agricultural systems that characterised the intensive farming of Valencia have revealed that they offered greater job opportunities and required more labour and capital and that, even though small family-run farms were their driving force, generated higher levels of productivity and wealth than other types of agriculture in Spain (Calatayud Reference Calatayud1989a; Simpson Reference Simpson1994; Palafox Reference Palafox2001; Calatayud and Millán Reference Calatayud and Millán2010). The expansion of intensive agriculture was based on high-yield crops that coexisted with subsistence crops and, most of all, on the growing use of the factor markets (Calatayud Reference Calatayud1989a, Reference Calatayud2001). As a result, the irrigated area of Valencia generated more prosperity in terms of employment and wealth. In fact, and as previously mentioned, there was a low incidence of emigration among the people from the irrigated area and its economy displayed higher growth rates (Calatayud Reference Calatayud2001). Other economic indicators, such as the evolution of agricultural exports, also suggest that the beginnings of the intensive and commercial agricultural model in the irrigated area of Valencia in the mid-19th century gave rise to an improvement in the biological welfare of its population. In Figure 1 we can observe that while exports of horticultural products began to rise in the 1870s, reflecting agricultural growth, height also increased, which was a symptom of the improvement of the biological standard of living.
Figure 3 also reveals that the rising trend in biological welfare slowed at the end of the 19th century. Among the birth cohorts of the end of the 1880s and the 1890s, the average height in the irrigated areas of Valencia stagnated. Considering that during these years the health and epidemiological conditions began to improve, expressed in a fall in the morbidity and mortality rates, particularly among children (Gozálvez Reference Gozálvez2003), the aforementioned stagnation in height can be explained, in part, by the moderate impact caused by the agricultural crisis at the end of the century. Apart from cereals, this crisis also extended to other crops characteristic of the irrigated area of Valencia, such as rice, raisins and, later, oranges (Piqueras Reference Piqueras1985), which would have affected the biological welfare of the population of the irrigated area of Valencia. A comparison between the exports of horticultural products and the evolution of average height reveals that, among the cohorts of the middle of the decades of the 1880s and 1890s, the stagnation of exports had a negative effect on the biological welfare of the male population in the irrigated areas of Valencia, which also stagnated.
Figure 3 shows that the conscripts born after the cohorts of the 1900s had higher biological standards of living. The average height of the birth cohorts of the 1900s and 1930s in the irrigated area of Valencia increased by almost 1.5 cm and the CV stood at 3.6 per cent. The increase in height indicates that there was an improvement in nutritional status. This anthropometric growth should have been related to a new economic and demographic cycle characterised by the progress made in commercial agriculture, the demand of nearby urban markets, the increase in agricultural exports and the fall in child mortality rates. There were dynamic sectors which reinforced employment and increased the income of farmers. The most spectacular case was that of horticultural products, such as onions (Garrabou Reference Garrabou1985; Piqueras Reference Piqueras1985, Reference Piqueras1999). In general, the situation of the agricultural sector in the region of Valencia was positive, particularly in the irrigated areas, as in addition to export growth there was also greater internal demand arising from the emerging urban markets (such as Valencia)Footnote 16 . Again, a comparison between the exports of horticultural products and the evolution of average height reveals that from the beginning of the 20th century, the former had a positive effect on the biological welfare of the male population. So, we can observe that the growth experienced in the heights of the cohorts of the 1900s coincided with the increase in exports in the 1900s and beginning of the 1910s (Figure 1). The health and epidemiological conditions also improved, as shown by regional and local studies, particularly after the decades of the 1890s and 1900s, which report a decrease in overall child (<1-year old) and youth (1-9 years old) mortality and an increase in average life expectancy, all in a context of a decreasing morbidity rate (Ferrater and Terol Reference Ferrater and Terol1996, pp. 269-271; Gozálvez Reference Gozálvez2003).
The cohorts of 1910, 1920 and 1930 were the generations that served in the army during the troubled years of the Second Republic, the Civil War and the early years of the Franco regime. Judging from the data represented in Figure 3, and far from what could be expected with respect to the poor economic and supply conditions at the end of the war and during the post-war periodFootnote 17 , the biological welfare of the conscripts of the irrigated area of Valencia improved. Even when hunger and poverty should have constituted the way of life for a considerable part of Valencia’s population at that time, the structure of land ownership in some areas (irrigated areas) and the good rhythm of agricultural exports after the 1950s were factors that may explain why the situation for the conscripts in this region differed from the general situation in the rest of Spain (Palafox Reference Palafox2001; Clar et al. Reference Clar, Martín-Retortillo and Pinilla2016). In general terms, the rural areas, due to the greater possibilities of accessing basic foods, enjoyed relatively higher biological standards of living than the urban centres during the initial years of the Franco dictatorship (Ayuda and Puche Reference Ayuda and Puche2014).
During the period of time analysed, economic inequality (height inequality measured with the coefficient of variation) diminished with average biological well-being (average height): the average height of the population increased by 3 cm throughout the period, while the coefficient of variation decreased by 0.4, indicating that height inequality declined (Figure 3). This was also the case for the two socioeconomic groups, farmers and farm workers (Figure 4).
To finish this section, we will analyse the average heights of the conscripts from the five selected municipalities (Figure 5). In general terms, and consistent with the findings of other provincial studies (Heyberger Reference Heyberger2007), differences may be observed between the heights of the different municipalities within an overall long-term upward trendFootnote 18 . The local differences in average height, which were acute in the mid-19th century, decreased among the cohorts of the beginning of the 20th century, probably due to economic progress and improvements in healthcare experienced by the five towns as a result of agricultural growth and the fall in morbidity and mortality rates, and increased again during the early years of the Franco regime.

4.2. Height and Inequality in Accordance with Access to Land Ownership
Was there biological inequality between landowners and landless farmers? Did the access to land ownership affect final height? Table 1 and Figure 6 show the contrasts in the average height of the rural conscripts of the irrigated area of Valencia in accordance with their access to land ownership among the cohorts born between the 1860s and 1930s. The results reveal that landowning farmers were always taller than landless farm workers, although they did not grow much more over time. Between the two dates, landowners and tenants grew by 4.8 cm and farm workers by 4.4 cm. The differences in height were very small in the mid-19th century, they increased at the end of the century (generations who did their military service during the 1900s and 1910s, in the final phase of the first wave of globalisation) and reduced relatively during the first-third of the 20th century. This reduction in inequality was more evident among the cohorts of the 1900s and 1910s, probably due to the progress made in the redistribution of income as a result of the developments in collective bargaining, particularly during the early years of the Second Republic (1931-33). In contrast, the height differences increased again, affecting the cohorts born in the 1920s and 1930s. This could be due to the negative effects of the Civil War, and particularly, Franco’s autarchy, which gave rise to an increase in poverty and inequality among the most disadvantaged social groups.

In Table 2, we can see the results of the ordinary least square estimates, robust to heteroskedasticity, of three models: the first refers to all the conscripts engaged in agricultural activities (14,199 rural conscripts), the second corresponds to farmers (10,493 conscripts) and the third to farm workers (3,706 conscripts), with the objective of identifying possible causes of biological differences between the two rural groups. The dependent variable is the height standardised at 21 years (in centimetres) and the explanatory variables are shown in the first column. The second and third columns show the estimated coefficients (Coeff.) and standard errors (SE), respectively, for the general model; the fourth and fifth columns show the estimated coefficients and standard errors for the farmers model; and the sixth and seventh columns for the farm workers model.

In the general model (14,199 conscripts) there is a dummy variable «Farmers», taking the value of 1 if the conscript is a farmer and zero if he is a farm worker, in order to distinguish whether there are differences between these two rural groups. As the «Farmers» dummy variable is positive and significant, even at the 1 per cent level of significance, we can conclude that there are some differences between these two rural groups, in favour of the farmers (0.4 cm). We have presented the two other models in order to distinguish between the two rural groups; farmers and farm workers.
The variables used in the estimates can be divided into four groups. The first group is called towns, composed of four dummy variables taking the value 1 if the individual was conscripted in this town and 0 if not, and their coefficients measure the difference between those born in this town and those born in the base town, which is Villarreal. According to our estimates, for the total sample size and for the farmers, Pego is the town with the highest figure for estimated average height and Gandía has the shortest estimated average height, but for the farm workers, the largest estimated differences in height are between those of PegoFootnote 19 and those conscripted in Alzira. The second group is called Decades of birth, composed of seven dummy variables taking the value of 1 if the individual was born in this decade and 0 if not, and their coefficients measure the difference in the average height between those born in this decade and those born in the base decade, which is that of those born between 1859 and 1869, while the rest of the variables remain fixed. According to our estimates, the farmers with and without land in the irrigated area of Valencia born in the decade 1930-39 were, on average, 3.6 cm and 3.3 cm taller than the birth cohorts of 1859-69, respectively. (Table 2, Decade of birth, columns 4 and 6).
The third group of variables measures differences in terms of Socio Economic Status (SES), such as the health status, the family situation or the access to educational resources. We can divide this group into two sub-groups of variables. The first sub-group includes the variables called Appeals for exemption where the base group is formed by the conscripts declared fit to serve and three dummy variables; Physical appeals (exempted) which is a variable that takes the value of 1 if the individual is declared exempt for physical appeals and zero if not; Social appeal (exempted) which takes the value of 1 if the individual is declared exempt for social appeals and 0 if not; and No appeal (exempted) which takes the value of 1 if the individual is exempt from doing military service but has not appealed. The second sub-group includes the variables that measure the Educational level of the conscripts. Illiterate constitute the base group and the Literate is a dummy variable taking the value of 1 if the conscript is literate and 0 if not.
The main results arising from the estimates are that the farmers with and without land who were excluded from military service due to physical problems were, on average, 3.2 and 1.6 cm shorter, respectively, than those farmers with and without land declared as fit to serve; those farmers with and without land who were declared exempt from military services due to social causes (family situation of poverty, elderly parents, being an orphan, etc.) were, on average, almost 1.8 cm shorter, respectively, than their counterparts who were declared fit for service; finally, those farmers and farm workers who were declared exempt from military service without having presented an appeal were, on average, 8.9 and 10.4 cm shorter, respectively, than those who were declared as being fit (Table 2, Appeals for exemption, columns 4 and 6). Our data reveal that there was a phenomenon that conditioned these strong differences: the high number of conscripts who were exempt due to their short heightFootnote 20 . In general, it can be deduced that these conscripts came from the most disadvantaged groups of Valencia’s rural society. The results are conclusive, as they indicate the decisive influence that health and poverty conditions and problems of physical growth had on biological welfare (Ayuda and Puche Reference Ayuda and Puche2014).
From the estimates of the coefficients of the variable that measures the level of education we can conclude that the land-owning and landless farmers who were literate were taller on average than those who were illiterate. More specifically, they were almost one centimetre taller (Table 2, Education, column 2). This difference in height between literate and illiterate people is wider among farmers than among farm workers (Table 2, Education, columns 4 and 6). The results of the models confirm that the positive relationship between literacy and height and access to education is related to a higher final average height and greater biological welfare (Martínez-Carrión and Puche Reference Martínez-Carrión and Puche2009; Ayuda and Puche Reference Ayuda and Puche2014).
The fourth and final group of variables contains those relating to the Place of birth, which, as a base group includes the natives and also four dummy variables to indicate immigrants from different areas. For example, Immigrant (Valencian region) takes the value of 1 if the individual was born in the Valencian region, but in a municipality different to the one where he was measured and 0 if not. From the estimate of their coefficients we can deduce that the place of birth and the unequal levels of economic development are important factors. The farmers with or without land born in the same municipalities as those where they were measured (natives of the sample) were taller than immigrant farmers with or without land, even with respect to immigrants from the same region. The immigrant farmers born in other municipalities in the region of Valencia were, on average, 0.7 cm shorter than the native farmers (Table 2, Place of birth, columns 4 and 6). The difference is remarkable, particularly if we take into account that some of these immigrant farmers could have been born in one of the five municipalities included in the sample, as well as other rural communities in the region of Valencia. With respect to the latter, it can be inferred that they could have emigrated from rural municipalities with environmental conditions that were relatively worse and with a less advanced agricultural sector. There is less doubt with respect to the comparison carried out between farmers with and without land who were immigrants born in other Spanish regions. The model reveals that the immigrant farmers born in Castilla-La Mancha and Andalusia were shorter, on average, than the farmers from the irrigated area of Valencia, specifically 4.1 and 2.3 cm shorter, respectively. With respect to the landless farm workers who were immigrants from these two regions in the centre and south of Spain, their average heights were 1.8 and 2.7 cm shorter, respectively, than those of the landless farm workers in the huertas of Valencia (Table 2, Place of birth, columns 4 and 6).
The econometric evidence corresponds to that observed in the Spanish agricultural historiography, which establishes the existence of different Spanish agricultures in virtue of variables such as the difference in productivity or the structure of ownership, among others (Gallego Reference Gallego1993). In the economic modernisation process, which took place between 1850 and 1930, certain territories clearly gained positions and others lost them to different degrees. The region of Valencia was an unquestionable winner, as it was then one of the most dynamic areas in terms of agriculture and the Spanish economy. Among the undeniable losers were Andalusia and Castilla-La Mancha, which had always remained within the parameters of a typically rainfed agriculture, with a predominance of traditional crops. Our results suggest that these differences were reflected in rural heights.
To end this section, we would like to examine in depth the role that access to land had on the biological welfare of the rural male populations of the irrigated area of Valencia between the 1860s and the end of the 1930s. To do this we have estimated three models in order to compare the influence of the variables analysed on the height of the two rural groups selected, farmers and farm workers, and whether this influence changed in different periods of time. The first estimate refers to the whole period of the study, while the second and third address, respectively, the cohorts born between 1859 and 1899 and between 1900 and 1939 (Table 3).

In Table 3, a single model has been estimated for all of the individuals with the objective of distinguishing the effects of the independent variables on the endogenous variable for the two categories, farmers and farm workers. We have also introduced a dummy variable multiplying each independent variable, Farmers, which takes the value of 1 if the individual is a farmer and 0 if he is a farm worker. If we analyse the first group of independent variables (Town), we can appreciate significative differences between the two periods. In the first period (1859-99), the differences within the same town between farmers and farm workers were significant in favour of the farmers in four of the five municipalities. However, in the second period (1900-39) these differences were no longer significant. With respect to the first sub-group of the set of variables that measure the effect of the SES (Appeals for exemption), the general model finds hardly any differences in height between the two rural groups in accordance with the appeals, although differences were found during the first sub-period. Of the cohorts between 1859 and 1899, the farmers who were excluded from military service because they had claimed to have physical problems were, on average, 5.2 cm shorter than the farm workers declared exempt for the same reason (Table 3, Model 2, column 4). But they were not only shorter, they also made more appeals (10.5 per cent as opposed to 2.9 per cent). What factors could explain this difference in height? It could be argued that a proportion of the land-owning farmers who lived during the period 1870-1910 experienced the economic improvements associated with the expansion of intensive and commercial agriculture, but their bodies suffered the effects of the agricultural growth period as a consequence of the intensive use of labour, the intensification of production and a possible relative reduction in food consumption. With respect to the second sub-group of variables which measure the effect of the SES on height (Education), the three models reveal hardly any significant differences in height between the literate land-owning farmers and landless farmers (Table 3, Models 1-3, columns 2, 4 and 6). The same can be observed in the last group of independent variables (Place of birth). However, there is one surprising result: although the coefficient is not highly significant, the immigrant farmers from Castilla-La Mancha were, on average, 2.1 cm shorter than the immigrant farm workers from the same region (Table 3, Model 1, column 2). In the rest of the immigrant groups there are no significant differences in height between farmers and farm workers.
In summary, from the estimates for the two sub-periods we can observe that in the first sub-period there are some differences between farmers and farm workers but, in the second sub-period the differences between farmers and farm workers were hardly significant which indicates that the inequality observed between these two groups diminished over time.
5. CONCLUSIONS
Based on the selection of five municipalities in the region of Valencia engaged in irrigated farming, this article has examined two issues related with the biological standard of living in Mediterranean rural Spain: first, the impact that the expansion of intensive and commercial agricultural and the agricultural growth process had on the physical welfare of the male population between the mid-19th century and the first-third of the 20th century; and second, the influence that the socioeconomic status, measured in terms of access to landownership, had on the final average height and on the social inequality of the rural communities. For both of these objectives the height data of the population of 41,841 conscripts, and a rural sample of 14,199 conscripts engaged in agricultural activities (10,493 farmers and 3,706 farm workers) between 1859 and 1939, have been analysed.
The anthropometric evidence shows that in the long term, the average height in the irrigated area of eastern Valencia increased by approximately 3 cm among the cohorts born between 1859 and 1939. The balance, in strictly biological terms, was positive. In this sense, one of the most relevant results that we have obtained is that, in contrast to what has been observed in other rural areas of Spain, the beginning of the production specialisation processes and the integration of the Valencian agricultural sector into the markets in the mid-19th century did lead to an improvement in the biological standard of living of the populations of the irrigated area of Valencia. As described in the article, the intensive agriculture of Valencia offered greater employment opportunities and required more labour and capital, and although small family-run farms were the driving force, they generated higher levels of productivity and wealth. Therefore, there was a low incidence of emigration among the people from the irrigated area of and its economy displayed higher growth rates.
In addition to the evolution of height and the hypotheses regarding its determinants, during the period under study, we have identified two significant facts: first, that economic inequality (height inequality) diminished while the average biological well-being (average height) increased. This has been observed for the whole male population and also for the two rural groups analysed in the irrigated area of Valencia (farmers and farm workers). The second fact is the existence of biological inequalities depending on the socioeconomic status. The study of height in accordance with access to land ownership reveals that, at least from the mid-19th century, land-owning farmers were taller than landless farm workers. The disappearance of aristocratic privileges and the formation of a market society gave rise to social differences which were reflected essentially in the economic domain, depending on wealth. In addition to the landowners and different tenants, there was another social group which had no access to ownership; the landless farm workers. The estimates carried out have revealed that for the cohorts of the second-half of the 19th century, the biological differences between land-owning farmers and landless farm workers were significant, while during the second period considered, the cohorts of the first-third of the 20th century, these nutritional inequalities between the two rural groups were not significant.
