Drawing on both gender regime theory and social reproduction theory, this article compares the socioeconomic and gendered organization of social reproduction in the United States and the United Kingdom from 1973 to 2013. Integrating data from the Luxembourg Income Study, the Multinational Time-Use Study, and additional sources, we examine how men and women of different socioeconomic groups contribute to social reproduction through household production, paid work, and government social benefits. Our results demonstrate that household social reproduction has not been universally refamilialized, marketized, or desocialized in either country. While there is some evidence of degendering, questions remain about its feminist implications.
