This data collection contains information on the characteristics of every single person admitted as an immigrant between fiscal years 1972-2000 (October 1971 through September 2000). Two types of immigrants are presented in this study. New arrivals who arrived from outside the United States with valid immigration visas and aliens who were already in the United States with temporary status and were adjusted to legal permanent residence. Variables include: age, sex, marital status, occupation, country of birth, country of last permanent residence, nationality, port of entry, month and year of admission, class of admission, state and area to which the immigrants were admitted, and others.
ResearchDataGov is a web portal and application system for discovering and requesting restricted microdata from federal statistical agencies. It was developed with support and guidance from the Census Bureau, the Office of Management and Budget, and the Interagency Council on Statistical Policy. Restricted microdata in RDG can be browsed by agencies and by titles. This tool provides guidelines for applying for restricted data. Resarchers can use the ResearchDataGov data access request system to apply for these data. ICPSR will then submit a completed application to the relevant federal agency.
