The history of the labouring family has gained increasing attention among European scholars in the last decades, but in Sweden, it remains an under-researched topic. Still, in the early modern period, labourers and their families made vital contributions to the country’s important mining industry. This paper examines the household economy of labouring families related to the mining industry in two Swedish areas in the late seventeenth century. On the basis on account books and court records, combined with demographic data, we explore the diversity of livelihoods and the complex web of interdependencies that made this economy feasible. We show that, while monetary remuneration was limited, wage labour in mines and metalwork gave the labouring family access to resources in the form of land, labour and credit beyond its own assets. Within the household, the man generally worked for wages, while his wife made use of the use-rights that came with his employment. The mining industry, and thereby also Swedish state finances, depended on this diverse family economy. In conclusion, interdependence, rather than the independent economic position described by classical models of early modern households, characterized the household economy of the labouring family.
