The growing importance of immigration in the United States today prompted this examination of the adequacy of U.S. immigration data. This volume summarizes data needs in four areas: immigration trends, assimilation and impacts, labor force issues, and family and social networks. It includes recommendations on additional sources for the data needed for program and research purposes, and new questions and refinements of questions within existing data sources to improve the understanding of immigration and immigrant trends.
