IPUMS-International and IPUMS-DHS crosswalk
Crosswalk geography variables identify administrative units in IPUMS-DHS countries that match those in the IPUMS-International census data. The variables correspond to the primary level of geography in both IPUMS-DHS and IPUMS-International. The spatially-consistent variables in the two databases allow researchers to summarize census data and attach it as contextual information to the DHS samples or vice versa.
IPUMS International geography corresponds to census geography as collected by the National Statistical Offices. The DHS project in most cases collects geographical information at the first administrative level of geography for the country. For several countries, the IPUMS International census geography matches the DHS geography, however there are variations, which lead to some detail being lost in the process of creating a spatially consistent geography and linking IDHS health data to IPUMS International census data.
The attribute data in the GIS files correspond to the codes that are found in the crosswalk variable for each country listed below.
