Abstract
This paper investigates the occupational implications of contemporary migration flows by region and race. Even though the expectation of a positive link between geographic and social mobility is a central tenet in the stratification literature, empirical assessments are rare and have produced inconsistent results. Our analysis departs from traditional frameworks by integrating both absolute and relative notions of occupational standing for evaluating migration outcomes, comparing migrants against non-migrant peers both at origin and destination. Results document that for whites, migration is associated with higher occupational attainment both in absolute and relative terms, irrespective of the regional direction of the move. For blacks, on the other hand, absolute occupational gains are markedly absent for migration to the South, which is instead characterized by significant improvement in relative terms. The differences in absolute and relative gains by race and direction of the move helps contextualize the considerable black over representation in north–south migration and highlight the implications of current internal mobility for racial stratification.

Notes
A difference between the international and internal migration case is worth highlighting. For international migrants, cultural, language, and other social discontinuities across societies are argued to prevent, or at least significantly delay, immigrants from comparing themselves to members of the host community. As a result, the community of origin remains the salient reference group. In the case of internal migration, on the other hand, the absence of language and rigid cultural barriers within most national boundaries means that internal migrants quickly substitute the reference group from origin to host communities (Stark and Taylor 1989). This reference group substitution is also implicit in Stouffer’s classic elaboration of relative deprivation.
To facilitate estimation, the white sample was further reduced to a quarter of the 5 percent sample, which yields a sample size comparable to the black sample (approximately 600,000).
Our historically grounded definitions are in fact very similar to the Census’ regional classifications, though our definition of the South excludes Maryland, West Virginia, and Delaware. While there has been considerable black mobility into Maryland between 1995 and 2000, it is not currently regarded as a southern state. West Virginia and Delaware have relatively small black populations and were never historical areas of black settlement. We tested models employing conventional Census Bureau definitions of regions and found substantive findings, particularly for the North–South comparison, did not vary across specifications.
It is important to note that this classification results in a heterogeneous group that combines primary, return, and repeat migrants; migration outcomes could vary across these groups.
Characteristics such as marital status and disability are measured in 2000 and serve as proxies for pre-migration characteristics, which are unavailable. It is possible that for some respondents, these characteristics changed in the five year interval during which migration is observed.
To illustrate, a resident of the South in 1995 that remains in the South in 2000 has a value of 1 for South95 and 0 for both North–South and South-North. A resident of the South in 1995 who moves north by 2000 has a value of 1 for South95 and 1 for the South-North mover dummy. A resident of the North in 1995 has 0 for all the variables. Thus, the effect for the South-North dummy (β 1 ) captures the difference in occupational standing associated with migrating south-north relative to southern non-migrants. In turn, a northern resident in 1995 that moves south has 0 for South-North and South95 but 1 for North–South, so the effect for the North–South dummy (β 3 ) captures the difference in occupational standing associated with migrating north–south relative to southern non-migrants. The effect for the South95 variable (β 7 ) captures overall differences in occupational opportunities across regions.
We report the estimates from the selection equation in Table 8 in Appendix 3. The determinants of migration are not the main focus of our analysis but allow us to control for unobserved factors jointly affecting migration and occupational outcomes. Results mirror those of prior studies with the likelihood of migration higher at intermediate ages and among those with greater educational attainment. Residents of areas with higher wages and homeownership rates are less likely to migrate, as are residents of the South.
