Each year, the Food Research & Action Center (FRAC) analyzes participation data in the Child and Adult Care Food Program (CACFP). FRAC uses U.S. Department of Agriculture data to develop a picture of participation trends in the U.S as a whole, each of the 50 states, and the District of Columbia. This report discusses changes in the number of CACFP child care centers and family child care homes over the past 20 years from fiscal year (FY) 1998 to 2018, the more recent changes from FY 2017 to FY 2018, and the overall increase in average daily attendance.
