 INTRODUCTION 
 
 This is a comprehensive listing of printed reports 
 published and issued by the Bureau of the Census as a 
 result of the 1970 Census of Population and Housing. 
 It was compiled for researchers as a guide to data 
 resources from the 1970 census. Each report is briefly 
 described providing users with basic information on the 
 source, purpose, contents, and geographic areas 
 covered in the reports. The figures, in particular, pro- 
 vide quick information on the availability of data for 
 specific geographic areas. Also included in the listing 
 are methodological reports, reference manuals, docu- 
 mentation, technical papers, and other reports related 
 to the decennial census. Figure 1 below is a summary 
 of the major reports related to the 1970 census. 
 
 To provide data users with key census information 
 as quickly as possible, the Bureau of the Census pub- 
 lished preliminary and advance reports, both subject to 
 revisions in the final reports. All data from the decen- 
 nial census are now available in final reports with hard- 
 bound volumes providing corrected population counts. 
 
 For information on obtaining the printed reports 
 listed here, unless otherwise indicated, write to the 
 Subscriber Services Section (Publications), Bureau of 
 the Census, Washington, D.C. 20233. The 1970 census 
 reports in the form of microfiche can be purchased 
 from the National Technical Information Service 
 (NTIS), Springfield, Va, 22151. The libraries in your 
 area may have copies of census publications for 
 reference use. 
 
 Inquiries regarding the data presented in any of the 
 reports listed here should be addressed to: Director, 
 Bureau of the Census, Washington, D.C. 20233.

 PHC(1), Census Tracts 
 
 This report series contains 241 reports each relating 
 to a particular standard metropolitan statistical area 
 (SMSA) in the United States and Puerto Rico and in 
 some cases certain areas adjacent to the SMSA. The 
 tables include population and housing data for the 
 component counties and places of 25,000 or more 
 inhabitants in the SMSA, as well as for the tracts. 
 Separate tables relate to the Negro population and to 
 persons of Spanish language, Spanish surname, or 
 persons of Puerto Rican birth or parentage for those 
 
 tracts that have a population of 400 or more of the 
 particular group. Each report includes census tract out- 
 line maps. 
 
 NOTE: About 100 other places and counties out- 
 side SMSA's were tracted; data for these non-SMSA 
 tracted areas were tabulated on the second and fourth 
 count summary tapes but were not published as 
 PHC(1 ) reports. Photocopies of the data from the tapes 
 are available, however; for further information, write

 counties (8 reports) and a United States summary. The 
 reports contain detailed socioeconomic data derived 
 from sample surveys conducted during the latter part 
 of 1970 and early 1971 on employment-related prob- 
 lems in low-income areas. Statistics are presented on 
 the demographic characteristics of the population by 
 the most important labor force and socioeconomic 
 factors, including value or rent of housing units and 
 number of rooms, by race and Spanish origin. 
 
 HC(2), Metropolitan Housing Characteristics 
 
 This series consists of 248 separate reports, one for 
 each SMSA (recognized as of February 1971) in the 
 United States and Puerto Rico, and a United States 
 summary. The data include detailed characteristics on 
 occupancy and vacancy, utilization, plumbing, struc- 
 ture, equipment and appliances, financial and house- 
 hold characteristics. SMSA's with large Negro or 
 Spanish-heritage groups have separate statistics for 
 those groups. The statistics are presented for the 
 SMSA, the central city, and other cities within the 
 SMSA with more than 50,000 inhabitants. 
 
 HC(3), Block Statistics 
 
 This series contains 278 reports, of which 236 re- 
 ports relate to specific urbanized areas. The remaining 
 42 reports relate to smaller cities, counties, etc., where 
 local authorities contracted with the Census Bureau to 
 collect, process, and publish the data on a block basis. 
 (Refer to Data Access Description No. 15 for a listing, 
 by State, of the areas for which block statistics were 
 prepared under the Contract Block Statistics Program.) 
 Data are shown for about 1.7 million city blocks. In 
 addition to housing data, the reports include some pop- 
 ulation data for each block. Each report has a set of 
 Metropolitan Maps showing in detail the location of 
 each of the numbered blocks in urbanized areas. 
 
HC(4), Components of Inventory Change

 istics of the components of change in the housing 
 inventory— new construction, conversions, mergers, 
 demolitions, and other additions and losses from 1960 
 to 1970 for the United States, regions, and the 15 
 largest SMSA's. Data are also given on the housing 
 units that remained the same during the period and on 
 the characteristics of units occupied by "recent 
 movers." The data are based on a sample survey taken 
 in the fall of 1970. 
 
 PC(S1), Supplementary Reports A 
 
 This series presents miscellaneous population data, 
 such as special compilations that could not be accomo- 
 dated in PC(1) or PC(2) as well as reproductions of 
 selected tables from those reports to permit distribu- 
 tion in an inexpensive format. (See figure 5 on p. 21.) 
 
 PC(V1-2), Advance Reports and 
 PC(P1-3), Preliminary Reports 
 
 These reports are superseded by the final reports, 
 PC(1)-AandPC(1)-B.

 PHC(3), Employment Profiles of Selected 
 Low-Income Areas (Rural Counties) 
 
 In addition to the reports shown in figure 3 for 
 cities, there are reports for selected rural counties (see 
 footnote 1 of figure 3 for list).

 State and the District of Columbia, regions, divisions, 
 individual SMSA's and their constituent counties, 
 central cities, and for each place of 50,000 or more 
 inhabitants. For each geographic area, counts of house- 
 holds are shown by tenure, whether owner or renter 
 occupied, and by race. Data for vacant units are shown 
 by vacancy status such as for sale only, for rent, and 
 other vacant. 
 
 HC(7) f Subject Reports

 shown in figure 6 on page 22. Detailed information and 
 cross-classifications generally are provided on a 
 national and regional level. 
 
 HC(S1), Supplementary Reports 
 
 This is an open series presenting miscellaneous types 
 of housing data and special compilations which could * 
 
 not be accomodated in the regular final reports, as well I 
 
as reproductions of selected tables from the large 
 reports to permit distribution in an inexpensive format. 
 (See figure 7 on p. 23.) 
 
 HC(V1), Advance Reports and 
 HC(P1), Preliminary Reports 
 
 Superseded by the final reports in the HC(1)-A 
 series. 
 
 METHODOLOGICAL REPORTS 
 
 PHC(E), Evaluation and Research Program 
 
 This open series of reports is designed to present 
 information on the accuracy of selected subject matter 
 or on the effectiveness of specific methodological 
 features of the census-taking process. Figure 8 lists 
 these reports as of August 1975- (See p. 23.) 
 
 PHC(R), Procedural Reports 
 
 This series of reports presents information on ad- 
 ministrative and methodological aspects of the 1970 
 Census. The reports are advance issuance of chapters 
 of the report, 1970 Census of Population and Housing: 
 Procedural History, PHC(R)-1. The PHC(R)-1 series 
 describes in detail most aspects of the 1970 census, 
 from its early stages of research and planning through 
 the tabulation, publication, and dissemination of the 
 final results, with each chapter focusing on a particular 
 stage. An index to the series is in preparation. The 
 PHC(R)-2 report is concerned with enumeration plans, 
 the PHC(R)-3 gives the geographic identification code 
 scheme and the PHC(R)-4 describes the procedures 
 used in the Surveys of Components of Change and 
 Residential Finance. 
 
 PHC(R)-1A, Procedural History: Advance Issuance 
 of Chapters 5 and 6— Chapter 5 discusses the field enu- 
 meration procedures (e.g., field organization and 
 personnel, training program, mail system, progress 
 reporting, enumeration costs, etc.) and Chapter 6 
 discusses the public information program. 
 
 PHC(R)-1B, Procedural History: Advance Issuance 
 of Chapters 13 and 14-Chapter 13 discusses the 
 efforts to carry out research on small-area data, its 
 applications, and assistance to census users (describes 
 the conduct of the New Haven Census Use Study, 
 DIME, ACG, GBF, etc.). This chapter also describes 
 the organization of the Data Access and Use Labora- 
 tory, which the Bureau established to carry out a 
 variety of communications, product development, and 
 documentation activities associated with new computer
