MCASEID is the unique identifier for each man in the men's sample for a given sample year. Using MCASEID and CLUSTERNOMN (MV001), analysts can link IPUMS-DHS data to the original DHS datasets to attach variables that are not currently available in IPUMS-DHS. For example, researchers can use MCASEID and CLUSTERNOMN (MV001) to link variables from the IPUMS-DHS with other variables from the men's file to merge country-specific variables, or to the Household or Couples Recode file to attach variables that are not yet part of IPUMS-DHS.
In most samples, users can identify men who are in the same household by using the first 12 characters of MCASEID (and CLUSTERNOMN (MV001)), as this indicates a unique household identifier.
MCASEID is created by The DHS Program using the variables CLUSTERNOMN (MV001), HHNUMMN (MV002), and LINENOMN (MV003). The last three characters indicate the male respondent's line number in the household file.
