The Care Work in the United States working group examines the social and economic implications of how care (child care, elder care, care for the disabled) is provided to dependent populations in the U.S. today. As women have moved into the formal labor force in large numbers over the last forty years, care work—traditionally provided primarily by women—has also shifted increasingly from the family arena into the formal economy. The working group will tackle the difficult policy problems that arise from the fact that market care is not a perfect substitute for family care.
