Prior research has shown that food insecurity is more common among U.S households with an adult who has a work-limiting disability than among other households. To provide more detail on the prevalence of food insecurity by a range of types of disabilities, we analyzed data from the Current Population Survey Food Security Supplement (2009 and 2010). We focused on two groups of households that include adults with disabilities: (1) households with a working-age adult with a disability that prevented work (not in labor force-disabled); and (2) those with a working-age adult with a specified disability (hearing, vision, mental, physical, self-care, or going-outside-home disability) and no indication that their disability prevented them from working (other reported disabilities). Food insecurity was most prevalent among households with an adult who was not in labor force-disabled (33.5 percent), followed by those with a working-age adult with other reported disabilities (24.8 percent). Households with no working-age adult with a disability had a much lower prevalence of food insecurity (12.0 percent). Close to two in five households with very low food security included an adult with a disability. The study findings demonstrate the importance of disabilities as a determinant of food insecurity.
