The increasing diversity of America's young children has important implications for Head Start and Early Head Start programs. This paper summarizes recent changes in the racial and ethnic composition of young children, particularly increases in Hispanic and Asian children, as well as shifts in where young children live, with some northeastern and Midwestern states losing children while southern and southwestern states are rapidly gaining. Based on these trends and recent Urban Institute research, the paper makes four recommendations about how local Head Start practitioners can best meet the needs of today's young children and their families.
