Perceived ethnic discrimination was studied by surveying 388 members of the Latino community in Chicago (115 Puerto Ricans, 162 Mexicans, and 111 Cubans). A factor analysis of how these Latinos perceived the treatment they got from 19 private and public social organizations (such as churches, libraries, and landlords) produced four dimensions of discrimination: regulatory organizations, consumer organizations, socialization organizations, and employment opportunity organizations. Age, years of residency in the United States, education, family income, and four media exposure variables (television, radio, Spanish-language press, and English-language press) were tested with hierarchical regression analysis on each discrimination factor. After controlling for the background variables, exposure to television was found to be a negative predictor of the discrimination perceived from the consumer and socialization factors. Exposure to the other types of media was not a significant predictor of any factor with such controls; but exposure to English-language press was positively associated with discrimination perceived from the regulatory and socialization factors. Age was the strongest negative predictor of the regulatory, consumer, and employment opportunity factors, while education was the only positive predictor (for the regulatory factor). (Author/RL)
