JUNE 1961. Library of Congress Card No. 4-18089 SUGGESTED CITATION U.S. Bureau of the Census, Statistical Abstract of the United States: 1961. (Eighty-second edition.) Washington, D.C., 1961. II PREFACE The Statistical Abstract of the United States, published annually since 1878, is the standard summary of statistics on the social, political, and economic organization of the United States. It is designed to fulfill two functions: First, to serve as a convenient volume for statistical reference; and second, to serve as a guide to other statistical publications and sources. The latter function is served by the introductory text to each section, the source notes appearing below each table, and the Bibliography of Sources (page 957). This volume includes a selection of data from many important statistical publications, both governmental and private. The publications cited as sources usually contain additional statistical detail and a more complete discussion of relevant definitions and concepts than can be presented here. Where contributing agencies are cited as sources, without mention of publications, more detailed information frequently is available from their unpublished tabulations and records. Statistics for Emphasis in the Statistical Abstract is given primarily to national data. Data for regions and individual States are presented to a lesser extent. Statistics for outlying areas of the United States are included in the State tables whenever available and supplemented by specialized information for these areas in section 33. cities or other relatively small geographic units appear only in a few instances. Wherever possible, statistics shown for the United States represent the 50 States and the District of Columbia. Figures for Alaska and Hawaii are presented separately in State tables, and are also included in United States summary tables, whenever such figures are available. Statements specifying inclusion or exclusion of the figures for Alaska and Hawaii appear in the headnotes to each table unless the inclusion or exclusion is self-evident. Data for Alaska and Hawaii are no longer presented in section 33, "Outlying Areas. . . .” Changes in the 1961 edition. This edition, the 82d annual issue, presents data for the most recent year or period available during the early part of 1961. Each year, in addition to the normal bringing up to date of the over 1,200 tables and charts included, new tables of current interest are introduced. Data that are less timely are eliminated and format and text changes are made where considered advisable. Special efforts were made in this edition to include new data from the 1960 Censuses of Population and Housing and the 1959 Census of Agriculture insofar as they were available by printing time. The sections thereby affected were Population, Construction and Housing, Agriculture (both sections), and Irrigation and Drainage. A more complete selection of statistics from decennial census reports covering these and other subjects will appear in the 1962 edition of the Abstract. Some changes were also introduced in the Distribution and Services section and the Manufactures section as a result of the availability of final figures from the 1958 Censuses of Business and Manufactures and Mineral Industries. The presentation of data on public welfare subjects was significantly increased by additions to the health and medical care subsections and to the Education, Social Insurance, and Prices sections. Eight new tables were added to the medical care group-five from the National Health Survey, showing information on dental visits, prevalence of acute and chronic conditions, utilization of health services, and persons requiring home care; two from the Bureau of Old-Age and Survivors Insurance, presenting data on medical care costs for the aged and how these costs are met; and one from the Bureau of Labor Statistics showing indexes of medical care prices. Six new tables were added to the Education section showing annual and lifetime income |
