A study examined the occupational differences between Hispanics and non-Hispanics. The study focused on the determinants of Hispanic occupational achievement; differences in the process of occupational achievement among different Hispanic ethnic subgroups; variations in the process of occupational achievement across geographic areas; and differences among the occupational achievement of Hispanics, Blacks, and non-Hispanic Whites. Data pertaining to earnings, steadiness of employment, and general job quality of Hispanic workers were compiled from various sources, including the 1970 Census of Population and the 1976 Survey of Income and Education. Once effects of schooling, experience, foreign birth, English language ability, location, and race are taken into consideration, data do not show differences in the earning levels of men's occupations among major ethnic subgroups of the United States Hispanic population. If the factor of foreign birth has any effects on occupational earnings potential, they appear to be mediated through English language ability. Furthermore, the effect of schooling on occupational earnings is about the same for Hispanic and non-White Hispanic men. For both groups schooling and length of labor force experience have only modest effects on occupational salary potential. Recommendations called for helping Hispanic men improve their English proficiency to fluency or near fluency. (MN)
