JUNE 1948. SUGGESTED BRIEF CITATION U. S. Bureau of the Census, Statistical Abstract of the United States: 1948. (Sixty-ninth edition.) Washington, D. C., 1948. II Use of the Statistical Abstract.-The Statistical Abstract of the United States presents in a single annual volume important summary statistics on the industrial, social, political, and economic organization of the United States, and includes a representative selection from most of the important statistical publications. It is, of necessity, limited primarily to national data and to limited summaries by States. It does not attempt to present the great wealth of local data available from many sources. This book is designed to serve a twofold purpose: First, to serve as a convenient reference volume for quantitative summary information; and second, to serve as a guide to various important sources of statistical data. If the user finds that the information given here on a particular subject is not sufficiently detailed for his purpose, it is suggested that he refer to the publication or the agency from which the statistics were obtained for publication in the Statistical Abstract. The source of each table is given at the foot of the table. The original source usually contains additional statistical detail, and a more complete discussion of the definitions and concepts involved, than can be presented in the Statistical Abstract; also, it may supply data for small areas. Further, the agency initially responsible for the statistics occasionally can supply still more detailed information on the basis of their unpublished tabulations or records. 1948 Edition. This edition, the 69th annual issue of the Statistical Abstract of the United States, is designated by the year of publication. The statistics shown are the latest available in the early part of the calendar year. The time periods or dates covered by the information in the tables vary according to the practices followed by the various agencies responsible for their preparation. The presentation of graphic material, begun in the 1947 edition, has been continued. Eighteen pages are now devoted to this type of presentation in comparison with 12 pages in the 1947 edition. This edition includes 1,070 tables in comparison with 1,059 in the previous edition. General notes have been added for Section 21, Waterways, Water Traffic, and Shipping, and Section 28, Construction and Housing. Additional or new subject material is presented on population forecasts, employment in the executive branch of the Federal Government, consumer income, motor fuel consumption, national forests, current industrial production, and size of establishments in the distribution and service industries. The listing of tables by source now follows the tabular material (see pages 984-987). A review of the materials presented in the field of insurance is in process and it is planned to incorporate the results in the next issue. Comments and suggestions relating to improvement of the current presentation of insurance data will be appreciated. Supplements to the Abstract.-The Statistical Abstract, as an annual onevolume publication, is of necessity limited in amount of detail shown. Businessmen, teachers, librarians, public officials, professional workers, and others often require data for individual cities, counties, metropolitan areas, and other small areas as well as for States. Economists, teachers, students, and others frequently need more historical information. To meet such requests for more detail, a series of supplements to the Abstract has been initiated. The first of these supplements, Cities Supplement-Statistical Abstract of the United States, provides 79 different items of information concerning the population, education, housing, labor force, business establishments, government finance, and climate of each of the 397 cities of the United States with 25,000 or more inhabitants in 1940. This supplement is on sale by the Superintendent of Documents, Washington 25, D. C., for 15 cents. The County Data Book, a supplement to the Statistical Abstract of the United States, is the second in this series. This publication brings together 91 different items of information for each of the 3,099 counties of the United States, with summaries for 138 metropolitan areas defined along county lines. Broad subject headings covered are population, labor force, housing, agriculture, industry, trade, and other economic data (including bank deposits, E Bond sales, war supply contracts, and wartime, facilities projects). This publication is on sale by the Superintendent of Documents, Washington 25, D. C., for $2.75. Historical Statistics of the United States, a third supplement, is now in press. This volume brings together 3,000 statistical series which extend back through time. Data are shown for each year back to 1789 or to the earliest data available for the series. In the preparation of this supplement the Bureau had the cooperation of a special committee of the Social Science Research Council set up to advise the Director of the Census on a source book of historical statistics and of the Committee on Research in Economic History under the auspices of the Social Science Research Council. These supplements to the Statistical Abstract have been prepared to extend the usefulness of the basic annual volume by assembling specialized material in separate books. As these supplements develop it will be possible to edit the material shown in the basic volume to emphasize recent data, while supplements will serve the more specialized needs. Responsibility.-As implied in the title, the contents of this volume are taken from a large number of sources, as indicated in the list of agencies furnishing material. (See pages 984-987.) The Bureau of the Census cannot accept the responsibility for the accuracy or limitations of the data presented here, other than for those which it collects. However, the responsibility for selection of the material for the general user and for proper presentation rests with the Bureau, even though carried out with the cooperation of many technicians who have given unselfishly of their time and knowledge in order to assist the Bureau's staff in making the presentation as meaningful and useful as possible. The cooperation of the users must also be acknowledged. Many persons have written offering suggestions for improving the presentation of the material. These letters have been most helpful and users are urged to continue to make their needs known. All suggestions will be carefully considered in planning future editions. FOR ADDITIONAL INFORMATION ON DATA PRESENTED write to the agency indicated in the source note to the table which covers the desired subject.
