IPUMS-International

http://www.ipums.org/international/

The first IPUMS-International database, released in May 2002, contained harmonized census microdata samples for Colombia, France, Kenya, Mexico, the United States, and Vietnam.  In March 2003 we added sample data from China. The current database includes fifty million persons with documentation covering temporal and international comparability issues, and is being disseminated to population researchers via a new web-based data access system.
