Differences in the incidence and duration of unemployment among Hispanic men and between Hispanics and Anglos were analyzed statistically. The investigation found that Hispanics were far more likely to be unemployed one or more times in 1975 than were Anglos. Differential treatment played a significant role in the higher unemployment of Hispanics, but differences in worker characteristics were far more important. There were substantial differences in unemployment among Hispanic ethnic groups: Mexican, Puerto Rican, and Cuban men had a higher incidence and longer average duration of unemployment than Central and South Americans and "other Hispanics." For Mexicans, lower schooling levels were the single most important factor. For Puerto Ricans, the large inflow of recent, increasingly rural, and unskilled Puerto Rican migrants contributed to their higher unemployment rate. Low education levels played an influential but secondary role. Cuban men were especially vulnerable, with higher probabilities of unemployment and multiple jobless spells than the other Hispanics.
