Federal and State employment data were examined in a study of the industrial, occupational, and job segmentation of Blacks, Hispanics, and Whites by sex in New York City's private sector. Primary focus was placed on the effects of the city's growing service-oriented economy on the employment patterns of Blacks and Hispanics. The study found that Blacks and Hispanics are poorly represented in the city's expanding core industries, even in nonsupervisory jobs. They are concentrated in lower-level jobs in peripheral industries, many of which are declining. With the exception of banks, insurance companies, telephone communications, and department stores, Blacks and Hispanics remain concentrated in their traditional bases of employment: Blacks are confined largely to health and social services and Hispanics are found primarily in the lower-paying nondurable goods and service industries. A key to many of the continuing employment problems of New York's Black and Hispanic workers is that Whites have increased their dominance in most of the city's expanding service-oriented industries while also increasing their share of employment in nonsupervisory jobs in all industries.
