Children of immigrants account for one in four (25%) young children in the U.S. Because their future prospects are important to all Americans, this report uses Census 2000 data to portray their lives. Results show that 93% of young children in immigrant families are American citizens who were born in the U.S., 56% have at least one U.S.-citizen parent, and 46% live in family-owned homes. They also live in strong families with vigorous work ethics. At the same time, many confront challenges associated with limited parental education and poverty, as well as constrained access to early education and low rates of health insurance coverage. Public policies can help ensure these children's success and their contributions to America when they become adults.
