To investigate the correlates of cross-state migration, we supplemented these analyses with evidence from 1% extracts of the Public Use Micro samples of the U.S. Censuses of 1970, 1980, 1990, and 2000 (Ruggles et al, 2008), using census respondents born in the US between 1948 and 1970, and tracking their apparent MLDA exposures and cross-state migration patterns based on state of birth and current state of residence.
