The major purpose of this monograph is to make available a substantial array of data regarding racial attitudes accumulated in a series of sample surveys taken by the Survey Research Center between 1964 and 1970. The first six chapters report the findings of a study undertaken in early 1968 in 15 major cities of the United States at the request of the National Advisory Commission on Civil Disorders, and supported by a grant from the Ford Foundation. Chapter seven summarizes data obtained in response to a set of identical questions asked of samples of the national population in the Fall of 1964, 1968, and 1970. The final chapter considers the implications of these findings for the future of race relations in this country. The 15-city study with which this monograph is primarily concerned involved interviewing 2945 white and 2814 black respondents between the ages of 16 and 69 from January through March of 1968. The three national surveys summarized in chapter seven were developed by the Center for Political Studies. These samples were drawn to represent the population of voting age in the continental United States, with a total of 1558 respondents in 1964, 1536 in 1968, and 832 in 1970. These three studies were mainly concerned with an analysis of voting in the national elections of those years; the small block of questions regarding race was included as incidental to that purpose.
