Unique person ID number


This is a 32-character string variable.


PERSONID is an IPUMS-constructed variable that uniquely identifies individuals in household and female files across all samples. PERSONID is a concatenation of the IPUMS-constructed variable HHID, a variable that uniquely identifies households, and LINENO, which is the person's reference number within the household.


There are no comparability issues.

Comparability with IPUMS-DHS

PERSONID in IPUMS-PMA is similar to the IPUMS-DHS variable CASEID, a sample-specific unique identifier for each woman in a given DHS sample year. CASEID is generally created by The DHS Program as a concatenation of the variables CLUSTERNO (sample cluster), HHNUM (household number), and LINENO (person's number within the household). A second IPUMS-DHS variable, IDHSPID, uniquely identifies persons across all samples, by concatenating the variables SAMPLE and CASEID.
