Food insecurity, a condition that affected 13.1 million U.S. children in 2015, is the limited or uncertain availability of nutritionally adequate and safe food.

About 84 percent of low-income, food-insecure households with school-age children partook in the USDA's National School Lunch Program, the agency reported.
A family of four with an annual income of $45,510 is eligible for reduced-price lunches and an annual income of $31,980 is eligible for free meals under the Federal Register's Child Nutrition Programs: Income Eligibility Guidelines. "Income" is considered before tax deductions.
To apply for free and reduced lunches, fill out a school meal application from your school or district.
