The primary concern in this paper is to analyze the effects of black p
opulation concentration on black and white men's relative and absolute
underemployment levels in labor market areas while controlling for th
e degree of occupational segregation by race. We draw hypotheses from
two primary bodies of research; one literature focuses on general raci
al competition and the other considers competition to be more limited.
Our findings that racial inequality in underemployment levels increas
es with blacks' population share are most consistent with the general
competition model. However, we also find some support for the limited
competition model which holds that not all whites benefit from increas
ed competition with blacks. Finally, we find that occupational segrega
tion helps to determine the form that racial discrimination in employm
ent adequacy takes. Where occupational segregation is high, black men
hold relatively more low-wage jobs, but where occupational segregation
is low, they experience higher levels of unemployment and more disadv
antage relative to whites.
