Background: The separate spheres, in which men dominate the public sphere of politics, arts, media, and wage work and women dominate the private sphere of unpaid production and caring, is a powerful configuration in much social theory (including Parsons, Becker, and Goode), which posited that with industrialization, family structures and activities would converge towards the nuclear family with strict gender roles.

Objective: This paper examines the major trends unraveling the gender division of family support and care that reached its peak in the mid-20th century, often called the ‘worker-carer’ or the ‘separate spheres’ model, by comparing the experiences of Sweden and the United States.

Methods: We use data that includes time series of macro-level demographic and economic indicators, together with cross-sectional data from censuses and time use surveys.

Results: The unraveling of the separate spheres began with the increase in the labor force participation of married women and continues with the increase in men’s involvement with their homes and children, but its foundations were laid in the 19th century, with industrialization. We show that despite short-term stalls, slowdowns, and even reverses, as well as huge differences in policy contexts, the overall picture of increasing gender sharing in family support and care is strongly taking shape in both countries.

Contribution: By doing a comparative, in-depth analysis, it becomes clear that the extreme role specialization within the couple that divided caring from ‘work,’ though theoretically important, applied only for a limited period in Northern Europe and the United States, however important it might be in other regions.
