This paper develops and tests hypotheses about the impact of opportuni
ty structures on black fertility across local labor markets. US Vital
Statistics and Census of Population data are combined and then examine
d with regression techniques to estimate the effect of both race-speci
fic and relative measures of opportunity structure on black fertility
in the United States. The results show that relative female opportunit
y structure has a negative relationship with black total fertility rat
es as well as with birth rates for specific points along the reproduct
ive age structure. However, the hypothesized relationship between rela
tive male opportunity structures and black fertility is not supported.
We discuss these results as they relate to minority fertility theory
and as they relate to public policy concerns.
