A few month ago, I tried to obtain data on county-to-county migration in the US but realized that this data might be to specific to find. Now I try my luck with a less detailed version:
I am looking for state-to-state migration data for each decade from 1950 to 1990. Ideally, this data would contain separate numbers of migrants moving from, say, California to Arizona and from Arizona to California (but for all state pairs in the US). In absence of that, I could also do with the total number of migration between any two states.
I am looking for separate data sets for 1950, 1960, 1970, 1980 and 1990 and any subset of these is highly appreciated.
