Censuses provide population numbers, household or family size and composition, and information on sex and age distribution. They often include other demographic, economic and health-related topics as well. The 2009 Vietnam de jure census collected data through direct enumeration on the subjects of housing, household demographics, employment for those 15 and older, education, disability, household deaths, and fertility for women 15 and older. The majority of the population was enumerated through the short form questionnaire while 15% of the population answered the long form questionnaire. The census day was April 1, 2009. A 15% differentially weighted sample of the enumeration area from the census (14,177,590 individuals) is available through IPUMS International at the University of Minnesota. Vacant units and group quarters are not identified in the sample. Refer to the IPUMS website for guidelines on citing database versions.
