Part I of a sociological study concerned with the urbanization of Mexican Americans (former migrant farm workers) in Michigan cities is presented. Using a random sample of Mexican American households, the following areas are examined: household composition and education, migration and community stabilization, finding jobs, employment and income patterns, and occupational and income mobility. Policy and research recommendations are presented in terms of the foregoing areas. The report suggests that "the role of cultural variables in the migration, resettlement, employment, education, and mobility of Mexican Americans must be considered in the varying situational contexts into which migrants move and within which they and their children live."
