From the website of the Inter-University Consortium for Political and Social Research: "The 1979 Chicano Survey, conducted by the Institute for Social Research, University of Michigan, was a household survey of persons of Mexican descent living in California, Arizona, New Mexico, Colorado, Texas, and Chicago, Illinois. The purpose of the survey was to compile a statistically representative and comprehensive body of empirical information about the social, economic, and psychological status of Chicanos. Interviews were conducted in Spanish or English, depending upon the respondent's preference. Major topics covered were mental and physical health and use of health services, family background and composition, customary practices and values, language use and attitudes, employment history, social identity, group consciousness, and political opinions and participation. The principal investigator was Carlos H. Arce."
