THE MEXICAN-AMERICAN STUDY PROJECT IS CONDUCTING INTERDISCIPLINARY, ANALYTICAL, AND DESCRIPTIVE RESEARCH TO EXAMINE THE SOCIOECONOMIC STATUS OF MEXICAN, SPANISH, AND MIXED INDIAN PEOPLE IN THE URBAN SOUTHWEST (IN 1960 SOME 3 1/2 MILLION). THERE ARE PLANS FOR AN EXTENSIVE INVESTIGATION OF THE EXTENT THAT THESE GROUPS ARE INTEGRATED INTO AMERICAN LIFE AND OF THEIR INDIVIDUAL RESPONSES TO SOCIAL CHANGES DURING THE PROCESS OF INTEGRATION. WORK HAS BEGUN ON A REVIEW OF RELEVANT LITERATURE, A COMPREHENSIVE ANALYSIS OF 1950 AND 1960 CENSUS DATA, AND ON FIELD STUDIES OF DIFFERENT COMMUNITIES TO INVESTIGATE HOW THESE COMMUNITIES FUNCTION FOR THEIR MEXICAN-AMERICAN POPULATION.
