Subject Reports from the 1970 Census of Population and Housing CONTENTS Page Introduction 1 Population Census Subject Reports .... 1 General Information 1 Contents of the Reports 2 Summary Tape Data for Population Subjects 10 Housing Census Subject Reports 10 General Information 10 Contents of the Reports 10 Summary Tape Data for Housing Subjects 13 Further Information 13 INTRODUCTION This Data Access Description presents infor- mation on the subject reports planned from the 1970 Census of Population and Housing. These reports concentrate on particular population or housing subjects and provide detailed infor- mation and cross- relationships for them. Two series of subject reports are being issued: Series PC(2), dealing with population subjects, and series HC(7), dealing with housing subjects. The population subject reports will constitute volume II of the population census reports and the housing subject reports will constitute volume VII of the housing census reports. Subject reports, both population and housing, are being issued on a flow basis as they are prepared and completed. Publication of these reports will be noted, as it takes place, in Small-Area Data Notes. Order forms for those reports already released are being mailed with this Data Access Description. Short paragraph summaries in this DAD list the data to be found in each report and the geographic areas covered. In general, however, space has not allowed the inclusion of any indication of the degree of detail within a particular data item. Frequently, extensive categories within an item have had to be com- pressed in this DAD to one simple term. For example, "occupation" as used here may refer to 12 major occupation groups, 157 intermediate occupation groups, 440 detailed occupations, or some number of selected occupations within these three basic categories. Use of the term only indicates that some type of occupation data can be found in the report. Such condensations were unavoidable in dealing with the vast mass of information embodied in the subject reports. (To give some idea of the appearance of the tables in the subject reports, two sample table outlines, one from a population report and one from a housing report, are included at the end of this DAD.) Previous Data Access Descriptions have described other 1970 census reports. Data Access Description No. 27, Printed Reports From the 1970 Census of Population and Housing, series CEP-4, described the following reports: Population Volume I, Characteristics of the Population (chapters A and B only); Housing Volume I, Characteristics for States, Cities, and Counties, and Volume III, Block Statistics; and the joint population-housing Census Tract Reports. Data Access Description No. 19, Printed Reports From the 1970 Census- Housing, Volume II, described that volume of the housing reports. The information on the subject reports from the 1970 Census of Population and Housing, as described in this Data Access Description (CEP-8), is subject to possible minor revision. POPULATION CENSUS SUBJECT REPORTS General Information As of this writing, 39 subject reports from the 1970 Census of Population are scheduled for publication by the end of 1973, and one more (No. 3B) is in planning for later release. This compares with a total of 38 issued as a result of the 1960 census. The 1970 reports, issued in the PC(2) series and constituting volume II of the population census reports, can be grouped into 10 broad subject areas: Ethnic groups, migration, fertility, marriage and living ar- rangements, education, employment, occupation and industry, income, low income, and geo- graphic areas. The titles of the 40 reports are listed by category in figure 1. 1 Most of the data in the population subject reports are at the national level, with many of them containing additional information for regions. A few contain data for smaller geo- graphic areas- -generally, States and SMSA's. A number of the reports have already been issued (see individual entries); most of the rest are planned for release during 1973. Contents of the Reports ETHNIC GROUPS 1A.
