Sex Ratio, Age and Ethnicity in the Atlantic Slave Trade: data from French shipping and plantation records*

  • David Geggus (a1)

Extract

This article examines the age and sex composition of the Atlantic slave trade in the belief it was of considerable significance in shaping black society in both Africa and the Americas. Focusing on the French slave trade, two main samples are analysed. One is composed of 177,000 slaves transported in French ships during the years 1714–92, which is taken from the Répertoire des expéditions négrières of Jean Mettas and Serge Daget. The other, derived from nearly 400 estate inventories, consists of more than 13,300 Africans who lived on Saint Domingue plantations in the period 1721–97. The results are compared with existing knowledge of the demo-graphic composition of the Atlantic slave trade to show the range of variation that existed through time between different importing and exporting regions, and to shed light on the forces of supply and demand that determined the proportions of men, women and children who were sold as slaves across the ocean. Significant and consistent contrasts are found between different ethnic groups in Africa and different slaveholding societies in the New World, many of them thus far unnoticed in the scholarly literature.

4 As the surviving data somewhat overrepresent the trade of the smaller French colonies, especially in the 1780s, it is useful to assign weights to the trade of each colony for each of the three periods used in Table 1, in order to reflect their true share of total French Caribbean imports. For this purpose the data in Curtin, P. D., The Atlantic Slave Trade: a Census (Madison, 1968), 166, 180 were used. The resultant changes are small. The overall sex ratio rises to 184, and the periodic ratios to 183, 172, and 200.

5 Robertson, and Klein, , Women, 4, 32, 39. In fact, in three of the four data-sets that Herbert Klein presents in this study males made up less than two-thirds.

7 The Pará/Maranhão statistics cited in Table 1 point to a fairly low sex ratio, but there is every reason to believe that this cotton-growing region supplied primarily from Cacheu and Bissau, and where the male/female price differential was negligible, was quite atypical. Census data indicate that slave sex ratios were much higher in other Brazilian provinces, but themselves are only crude guides to the composition of slave imports. Conversely, some sources mention large numbers of women and youths among Brazilian slave imports. See Carreira, A., As companhias pombalinas de navegaçao (Porto, 1969), 92, 161–8; Conrad, R., World of Sorrow (Baton Rouge, 1986), 912; Schwartz, S., Sugar Plantations in the Making of Brazil (Cambridge, 1985), 348–53; Miller, J., ‘Slave Prices’, in Lovejoy, P. (ed.) Africans in Bondage (Madison, 1986), 57, 61, 72; Miller, J., Way of Death: Merchant Capitalism and the Angolan Slave Trade, forthcoming, 130, 163–4. In the 1983 edition of his study, Carreira states that the data are too unreliable for analysis.

10 On the seventeenth century French slave trade see, Gautier, A., Les soeurs de Solitude: la condition féminine dans l'esclavage aux Antilles du xviie au xixe siècles (Paris, 1985), 80, which states that around 1660 French slavers carried an equal number of men, women, and children; also Petitjean-Roget, J., La société des habitations à la Martinique (Lille, 1980), vol. 2, 1448.

11 Males amounted to 71.5 per cent of total imports into Havana during the period 1790–1820 only by virtue of local importations of Creole slaves from other islands: Robertson, and Klein, , Women, 32–3. A slightly lower proportion is given in Klein, , Middle Passage, 222.

12 These were the two later Dutch trades, and the British trades to Barbados, 1663–67, to the British Caribbean, 1673–1723, and to Spanish America, 1715–38.

13 See above, note 4.

14 French planters generally classed as adults those seemingly aged fifteen and over, as did British traders of the late seventeenth and early eighteenth centuries: Davies, K. G., The Royal African Company (London, 1957), 300. In Dutch practice, the adult classification began at age sixteen: Gemery, H. and Hogendorn, J. (eds), The Uncommon Market: Essays in the Economic History of the Atlantic Slave Trade (New York, 1979), 256. In late eighteenth century trade to Jamaica, a height of 4 4 was the criterion used. This suggests an age range for children of about 0–11 or –12 years. Cf. Friedman, G., ‘The heights of slaves in Trinidad’, Social Science History VI, 4 (1982). For Latin American practice, see Klein, , Middle Passage, 223; de Queiros Mattoso, K. M., Etre esclave au Brésil, xvie–xixe Steele (Paris, 1979), 97.

15 Unfortunately, the relative proportions of young children and teenagers were not at all constant. In the Cuban trade children under eleven were much more numerous than those aged eleven to seventeen. However, among imports into Parã/Maranhão the opposite was true, and in the British trade to Spanish America, 1715–35, children under ten were greatly outnumbered by those aged ten to fourteen. This also seems to have been the case in Saint Domingue.

16 Klein, in La traite des noirs, 85. The extremely low percentages of children reported in Portuguese records prior to 1811 seem scarcely credible in view of the very high percentages obtained for the post-1811 period from more trustworthy sources. Note also the uncertainty surrounding the British trade of the 1790s: above, table 1, n. 13. Cf. above, note 7, and Miller's, J. comments in Actes du Colloque International sur la Traite des Noirs, Nantes, 1985, 2 vols., forthcoming, vol. I, 133.

21 It is perhaps relevant that, while Africans described as Congos and Igbos had approximately the same average height in the British as in the French colonies, Man-dingoes in Jamaica were three to four inches shorter than in Saint Domingue and Trinidad: Geggus, D., Saint Domingue Slave Revolt, forthcoming, ch. 2.

29 However, the rise in sex ratio may also have been due to increased numbers of Hausa slaves being sent down the Niger to Brass and New Calabar.

30 Sample sizes were as follows: 1716–53: 10,897; 1764–78: 47,317; 1784–92: 4,851.

31 Children, apparently aged under seven or eight, dropped from 127 per cent of exported slaves in 1733–5, to 7.7 per cent in 1749–52, and for the period 1734–59 made up 72 per cent. After 1759, children formed under 1 per cent of those recorded. See Goulart, M., Escravidão africana no Brasil (São Paulo, 1950), 203–9. This latter reduction may derive partly from the introduction of a new system of record-keeping, which henceforth took no account of babies. They, however, had represented less than 2 per cent of the 1733–5 and 1749–52 samples.

32 See Peukert, W., Der atlantische Sklavenhandel von Dahomey, 1740–1797 (Wies-baden, 1978), 6465; Law, R., The Oyo Empire, c. 1600–c. 1836 (Oxford, 1977), 222–3.

33 Sample sizes were Porto Novo and Badagri: 4,028; Bight of Benin: 41,121. Slaves exported from Epe in the middle of the coast had a demographic profile midway between those of the eastern and western ports.

34 Prior to Eltis's recent Economic Growth, which finds a comparable pattern for the nineteenth century, only Inikori, Forced Migration, 23 recorded a low regional sex ratio – among 4,813 slaves shipped from Whydah to Jamaica in the period 1764–88. Data showing a relatively high sex ratio, but deriving from more restricted samples, appear in Robertson and Klein, , Women, 33, and Lovejoy, , Transformations, 62.

40 Curtin, , Senegambia, vol. I, 176; Geggus, , ‘Slaves’, 23–4. However, the extremely high regional sex ratios Curtin found in the 1680s and 1720s would appear quite unusual.

43 Because of the uneven importance of a foreign contraband slave trade in different parts of Saint Domingue, and the contrasting preferences displayed by planters of different crop-types for slaves of certain ethnic groups, the ethnic make-up of the slave population was subject to substantial local variations. Future efforts to reconstruct the ethnic composition of the French slave trade from these sources need to take this into account: Geggus, , ‘Slaves’, 1423; Geggus, , ‘Les esclaves de la plaine du Nord à la veille de la Révolution française, IV,’ Revue de la société haitienne d'histoire, 149 (1985), 23; above, note 9.

45 Both ‘Miserables’ and ‘Mesurades’ were as yet unidentified peoples from the area of Cape Mesurado. The latter were also known in the South and West Provinces of Saint Domingue as ‘Canga’, an Akan term meaning ‘barbarous outsider’. It was seemingly bestowed on them by their easterly neighbours, who were more numerous in those parts of the colony, being introduced by British contraband slavers.

46 See the data in Higman, ‘Trinidad’, table 2, in Crahan and Knight, Africa. Unfortunately, Higman gives only regional but not ethnic sex ratios.

47 See Geggus, , ‘Slaves’, 1720, 24, 30.

48 Akan and Ga speakers were known as ‘ Coromantees’ in the British West Indies, where they were quite numerous and highly prized. ‘Caramenty’ were rarely found outside those parts of Saint Domingue where the contraband slave trade flourished: Geggus, D., ‘On the eve of the Haitian revolution’, in Heuman, G. (ed.), Out of the House of Bondage: Runaways, Resistance and Marronage in Africa and the New World (London, 1986), 122.

49 Although the French distinguished ‘Aoussa’ from ‘Gambary’, I follow Law, , Oyo Empire, 227n in assuming that the terms were synonyms, ‘Gambary’ being the Yoruba word for Hausa.

50 The sole exception would seem a footnote in Gautier, Soeurs, 80.

51 Robertson, and Klein, , Women, 61.

52 Although numerous peoples were no doubt enveloped in the generic term ‘Congo’, a majority were probably Kikongo speakers, either native or ‘naturalized’. This is suggested by linguistic evidence from colonial and modern Haiti. The chief sub-groups identified in colonial records, apart from Kongo, were Nsundi, Yombe, Mbala and Yaka. While regional trade routes extended far into the interior, there is little evidence even in the nineteenth century that the most distant sources supplied many captives to the coast: Curtin, , Census, 256, 295–6; Degrandpre, L., Voyage a la cote occidentale d'Afrique fait dans les années 1786 et 1787 (Paris, 1801), vol. I, xiv–xxv, vol. 2, 37, 48. For a contrary view see Miller, Way of Death. Among the ‘ Mozambiques’ the only peoples identified were Makonde and Makwa.

53 Igbo constituted 91 per cent of the region's slaves in the French plantation sample; but only 52 per cent in the 1813 Trinidad sample (excluding Hausa); and 68 per cent in a sample of 1,008 slaves sold in 1821–2, 26 per cent being Ibibio: Northrup, D., Trade Without Rulers (Oxford, 1978), 231. Although the latter sample, drawn from only two ports, is not strictly representative, it is broadly corroborated by the 1848 Sierra Leone census of freed slaves, which similarly shows a much increased ratio of N. W. Bantu to Igbo: Northrup, , Trade, 60–1.Eltis, , Economic Growth, 358–9, however, found that in this period Igbo and Ibibio captives exhibited similar sex ratios.

54 In West Africa with the exception of Senegambia the coastal price of adult males in the eighteenth century usually exceeded that of adult females by 25 to 40 per cent: Atkins, J., Voyage to Guinea, Brasil and the West Indies (London, 1735), 163–6; Barbot, J., Description of the Coasts of North and South Guinea (London, 1732), 326; Peukert, , Sklavenhandel, 112; Curtin, , Senegambia, vol. I, 173, 176; below, note 83.

56 Descriptions of the sexual division of labour were taken from Murdock, G. P., Ethnographic Atlas (Pittsburgh, 1967); Vansina, J., Ethnographie du Congo (Kinshasa, nd), 14; Manning, , Dahomey, 7071. American planters frequently found the women among their Igbo and Congo slaves better fieldworkers than their male counterparts, whereas among Bight of Benin slaves males and females were equally prized: Edwards, B., History Civil and Commercial of the British West Indies (Dublin, 1793), vol. 2, 68, 70; Littlefield, , Rice, 18, 151; de Saint-Méry, Moreau, Description, vol. I, 51, 53; Malenfant, C., Des colonies modernes (Paris, 1814), 210–11; Long, E., History of Jamaica (London, 1774), vol. 2, 403–4; Ducoeurjoly, S., Manuel des habitants de Saint Domingue (Paris, 1802), vol. I, 24. Some also made the same observation of the Akan-speaking ‘Coromantee’: Long, , Jamaica, vol. 2, 446, 471–3.

60 Of course, the two categories were not necessarily mutually exclusive. See Edwards, , History, 5659; Long, , Jamaica, vol. 2, 473; de Saint-Mery, Moreau, Description, vol. I, 48, 50.

61 Originally advanced by J. D. Fage, this view is espoused in Manning, , Dahomey, 32, 42, and Northrup, , Trade, 80–4.

62 This is argued in Thornton, , ‘Angola’, 426–7; A. van Dantzig, ‘Effects of the Atlantic slave trade on some West African societies’, in Inikori, , Forced Migration, 200; Lovejoy, , Transformations, 64–5.

76 See Table 1; above, note 10; Dunn, R., Sugar and Slaves: the Rise of the Planter Class in the English West Indies (London, 1973), 316; French Caribbean censuses in Arch. Nat., Aix en Provence, GI/509.

77 Littlefield, , Rice, 5666, 72.

78 See above, note 9.

79 Despite a large urban market for female slaves, Spanish American demand was usually considered by contemporaries strongly pro-male: Littlefield, , Rice, 5960. Cf. Table 1. The two French slave cargoes listed by Mettas that were sold in the Spanish Caribbean significantly had a sex ratio of 204:100.

81 See, Klein, , Middle Passage, 222–5; Fraginals, Moreno, ‘Africa’, 192–3; Eltis, , Economic Growth, 257.

82 Klein, , Middle Passage, 32–4.

83 Isolated data suggest that on the Gold Coast the male:female price ratio rose between 1720 and 1770 from about 100:67 to 100:80, then fell back to around 100:77 in the mid-1770s as slave prices declined: see Littlefield, , Rice, 62n; Metcalf, G., ‘Gold, Assortments and the Trade Ounce: Fante Merchants and the Problem of Supply and Demand in the 1770s’, J. Afr. Hist, XXVIII (1987), 37.

84 LeVeen, , Suppression, 117–21; Manning, , Dahomey, 37. Eltis, Economic Growth, passim. The widening gap between African and American slave prices may additionally account for the high percentages of children that also were a feature of the nineteenth century trade.
