The United States Census Bureau periodically issues brief reports highlighting research based on the latest Census; this particular report deals with the changing demographics of the older foreign-born population in the United States. Based on a random sample of 57,000 households, the 19-page report contains information about socioeconomic characteristics of this cohort, including marital status, their geographic distribution, and their participation in social assistance programs. The report was authored by Wan He, who also commented that, "Historically, Europe has been the primary source of immigration to this country, and the European-born was the single largest group among the older foreign-born population in 2000." This report will be of great interest to demographers and persons working to develop public policy programs dealing with the aging.
