Approximately 1-in-7 people and 1-in-4 children received benefits from the US Supplemental Nutrition Assistance Program (SNAP) in July 2011, both all-time highs. We analyze changes in SNAP take-up over the past two decades. From 1994 to 2001, coincident with welfare reform, take-up fell from 75%...
