I’ve been researching residential mobility using IPUMS-CPS ASEC (and IPUMS-USA, et al.) and I’ve noticed that there are gaps in availability for MIGRATE1 (available 1963-1971, 1976, 1981-1984, 1986-2019), but in one of the years in which it is available, 1995, it seems very wonky.
Here’s a table of year and migrate1 from 1993-1998 using asecwt as the probability weight in Stata:
(The same patterns appear with unweighted counts)
Can anyone provide any insight as to why 1995 has substantially higher counts for NIU and all the mobility types, but substantially lower counts for ‘same house’? It throws the percentages way off, e.g. the mobility within county goes from 10% to 23%.
