I’m trying to link individuals’ responses across consecutive ASEC samples for every 2-year stretch from 1989 to the present. Some forum answers suggest using CPSIDP as the primary linking variable for consecutive ASEC samples, while others suggest using HRHHID and HRHHID2. Is one of these methods preferable to the other at this time? I’ve tried using CPSIDP, and this generally results in a match rate of about 30-35% between years, after confirming using race, sex, and age (this is after dropping individuals who were part of the ASEC oversample; otherwise the rate would be much lower). Might any other method result in a higher match rate?
A few sub-questions:
Is it possible at this point to link individuals’ ASEC responses across years before 1989? This postfrom last year suggested this capability might be on the way.
Is there any way to link individuals across consecutive ASEC years if they are part of the oversample (and thus have no CPSIDP identifier)?
