Immigration Statistics: Guidance on Producing Information on the U.S. Resident Foreign-Born, Report to Congressional Requesters [open pdf - 81KB]
"The makeup of the foreign-born population residing in the United States continues to interest policymakers as they debate immigration issues. These policymakers have expressed concerns that the information necessary to make informed decisions on public policy regarding immigration either has not been available or has not been adequate. Accordingly, you requested that we review the federal immigration statistics function. You asked us to follow up on two reports of the National Academy of Sciences (NAS) that contain recommendations designed to streamline and strengthen the collection, analysis, and dissemination of immigration statistics, assess the quality of current federal demographic information on the foreign-born population, and identify the federal guidance on the production of demographic information on foreign-born residents and provide information on agencies' status relative to that guidance. This report responds to the third objective of your request."
