IPUMS IHGIS

IPUMS IHGIS released data tables and GIS boundary files for an extended time series of the Population and Housing Census for Ireland covering five censuses: 1966, 1971, 1979, 1981, and 1986. We also released data tables and boundary files for the Chad 2009, Jordan 2015, and Zambia 2000 Population and Housing Censuses.

IPUMS CPS

IPUMS CPS has created three new variables: PLACECENSUS and PLACEFFIPS report Census codes for central/principal cities in selected metropolitan areas, and MULTGEN helps identify the number of distinct generations contained within each household. We have also integrated additional variables for the Tobacco Use supplement, including variables on e-cigarette use, and additional variables from the Veterans supplement.

IPUMS NHGIS

NHGIS geographic crosswalks are now available for six more levels: places, county subdivisions, ZIP Code Tabulation Areas (ZCTAs), metropolitan & micropolitan statistical areas, urban areas, and Public Use Microdata Areas (PUMAs). The new crosswalks provide interpolation weights to allocate data from one year’s census blocks to one of these six unit types as defined in a different year (1990 to 2010, 2000 to 2010, 2020 to 2010, or 2010 to 2020
