question about HRHHID and HRHHID2


#1

If I use CPSID to match household in time dimension. Do I need to care about HRHHID2 and HRHHID ?


#2

Using the concatenation of HRHHID and HRHHID2 can uniquely identify households within basic monthly samples. Whereas, the CPSID variable, uniquely identifies households across basic monthly samples. The key difference here is if you are using multiple monthly samples and want to link households, then you’ll wan to use the CPSID variable.
