A report by the Federal Reserve Bank of San Francisco examines the drivers of the recent rise in involuntary part-time employment and the impact that trend has on lower-income households, focusing on the interrelations among housing, jobs, transportation and child care. Currently, more than six million Americans are involuntary part-time workers, and 19 percent of part-time workers are living in poverty. The report suggests that access to full-time employment is not only constrained by the availability of full-time jobs, but also by access to affordable housing near jobs, transportation and child care.
