Food insecurity, which affects an estimated 15 million Americans is the limited or uncertain availability of safe and nutritionally adequate foods, or the limited or uncertain ability to acquire acceptable foods in socially acceptable ways. Food insecurity has been consistently associated with poor health outcomes in children, including poorer overall health status, acute and chronic health problems, and limited healthcare access. This report describes the percentage of children aged 0-17 years living in food-insecure households during the past 30 days by selected sociodemographic and family characteristics using 2019-2020 National Health Interview Survey data.
