This research examines the extent of poverty among working men in urban lab
or markers and analyzes differences in the risk of working poverty among Me
xican, puerto Rican Cuban, and non-Latino White men. Using data from the 19
90 Public Use Microdata Sample, the research documents sizable ethnic diffe
rences in rates of working poverty and ascertains the extent to which those
differences are explained by labor market attachment, human capital employ
ment position, and labor marker context. Labor force attachment clearly red
uces the risk of poverty for men but levels of attachment do not explain et
hnic differences in poverty among workers.
