In this paper we look at the use by construction workers and their families in the United States of five means-tested safety net programs. We find that 39% of families of construction workers are enrolled in one or more safety net program at a cost of almost $28 billion per year. In comparison, 31% of all workers have a family member enrolled in a safety net program. Three times as many construction workers as all workers lack health insurance (31% compared to 10%).
