Geographic tools for IPUMS-DHS
IPUMS-DHS provides both harmonized (integrated) and year-specific geographic variables. Harmonized variables provide consistent geographic units for a country across samples years, facilitating comparisons across time. Year-specific variables retain all geographic detail from each sample and are not consistent over time.
Geography crosswalks to IPUMS International census microdata
The spatially consistent variables at the primary level of geography within countries allow researchers to summarize subnational census data from IPUMS International and attach them as contextual information to IPUMS-DHS samples, or to summarize DHS data to censuses.
