Indices of racial segregation in employment are presented for black and non-Hispanic white workers in the same occupational category. Controlling on the availability of blacks in each category, the most racially segregated groups are laborers and service workers. At each occupational level, women are more racially segregated from one another than are men, although differential employment in high- and low-segregation industries accounts for some of these differences. The racial composition of an establishment's work-force in one occupation is strongly related to its racial composition in other occupations, particularly though, within the blue collar and white collar subgroups. The black proportions of sales workers and clerical workers are higher the more the total establishment's employment is concentrated in that occupation. Further research directions are suggested.
