The history of work is marred by the fact that the meaning of “labour” or “work” changed with the arrival of modern society, making it difficult to draw comparisons across time. There has been a shift from understanding work as any activity that may secure continued living and well-being, to seeing it as paid, full-time, specialized employment. This transformation has obscured the work of some groups in society (notably women but also others) and work in the form of multiple employments (which often means multiple labour relations). The methods and sources presented in this Special Theme offer valuable tools for historians seeking to address and navigate these issues.

It has long been recognized that, in order to understand economies in the past, we need better information about women's work and tertiary sector work. It is also well known that, while valuable in many ways, nineteenth-century censuses give incomplete information about women's contributions to the economy. Consequently, censuses are a poor basis for estimating the occupational structure. This article offers a solution to these problems by triangulating census data with qualitative information extracted from court records. The result is a more reasonable estimate of the first-level occupational structure in a Swedish local society (Västerås and its surroundings) around 1880. This estimate suggests that just before the onset of industrialization, around eighty per cent of the adult population, women and men, were active in primary and tertiary sector work. Compared to the census, the analysis sets women's share in the primary and the tertiary sectors at higher levels. The article has a strong methodological focus and describes in detail how the court records were analysed and adjusted to be comparable with the census.

In this article, which has a strong methodological focus, we establish the labour relations that characterized the urban population of the Swedish town of Västerås in 1820. Several sources are combined: the so-called Tabellverket (an early form of demographic statistics) and observations made in, primarily, local court records. To assign labour relations as defined by the Global Collaboratory on the History of Labour Relations project, the preliminary picture based on the Tabellverket is complemented by systematically adding information from court records analysed in the Gender and Work project. This information captures both what people did and also, to some extent, what labour relations they were involved in. Subsequently, all the information is collated to estimate the labour relations characterizing the whole population in the selected town. The result of this experiment is a much more encompassing and richer picture of the labour relations within the selected community, one that acknowledges both women’s work and multiple employments. In a broader perspective, the case study contributes to our understanding of the gradual increase of commodified labour in the world.

This article reflects on the pitfalls of the combined search for big and better data and argues for more attention to everyday experiences and incidental evidence. It proposes that including spatial aspects, perspectives from cultural, colonial, and women’s history, as well as widening the source base helps to remedy these challenges, and encourages historians to abandon their hesitations and embrace the uncertainties in doing so. It draws on the results of a research project at the University of Amsterdam that utilizes incidental evidence to enhance our understanding of gendered spatial patterns in premodern cities.
