Trends in Income Insecurity Among U.S. Children, 1984–2010. Bruce Western, March 4, 2016, Paper. "Has income insecurity increased among U.S. children with the emergence of an employment-based safety net and the polarization of labor markets and family structure? We study the trend in insecurity from 1984–2010 by analyzing fluctuations in children’s monthly family incomes in the Survey of Income and Program Participation. Going beyond earlier research on income volatility, we examine income insecurity more directly by analyzing income gains and losses separately and by relating them to changes in family composition and employment."
