Trends in the relative occupational status of African Americans and European immigrants in Northern cities, 1880–1970

In his classic book, A Piece of the Pie, Stanley Lieberson described divergent trends in occupational standing for African Americans and European immigrants after 1920, as the Great Migration from the South swelled the size of the black population in northern cities. In this paper I build upon Lieberson’s work using longitudinal data drawn from the Integrated Public Use Microdata Series for the census years 1880–1970. This more versatile data source allows me to examine separate occupational trends for northern-born blacks and southern-born migrants and to control for relevant socio-demographic characteristics. The findings confirm Lieberson’s general conclusion that blacks lost ground, occupationally, to immigrants after 1920. However, they show further that: (1) northern- and southern-born blacks experienced different trends in relative occupational standing after 1920, (2) that these different trends were due largely to compositional differences between the two groups of northern blacks, especially educational differences, and (3) that blacks were generally less successful than immigrants at translating additional educational attainment into improved occupational status, with southern migrants experiencing the weakest occupational returns to education. It is concluded that compositional differences and a racially-defined occupational queue were the most important factors shaping group differences and trends in occupational standing between 1920 and 1970. Timing of arrival in the northern industrial economy and a response by whites to the “racial threat” from a growing black population were less important.
