The major portion of the information on the population of this tate, compiled from the Censuses of Population and Housing of 950, is presented in this volume. It contains three chapters reviously published as separate bulletins. Chapter A recapitutes the statistics on the distribution of the total population within he State (originally published in the Series P-A bulletin and in olume I); Chapter B presents statistics on the general charactertics of the population of the various political subdivisions of the tate, such as counties and cities, as well as of standard metropolan areas and urbanized areas (originally published in the Series '-B bulletin); and Chapter C presents data on the detailed charcteristics of the population of the larger areas within the State originally published in the Series P-C bulletin).

The major part of this volume is devoted to the presentation of formation on the characteristics of the population. Statistics n the general characteristics contained in Chapter B include data n urban-rural residence, age, sex, race, nativity, citizenship, ountry of birth, school enrollment, years of school completed, marital status, residence in 1949, employment status, occupation, ndustry, class of worker, and family income. In Chapter C, nformation on most of these characteristics is presented again out in greater detail. The statistics in Chapter C include crosslassifications of age with race, nativity, citizenship, marital status, elationship to household head, education, and employment tatus; the occupational and industrial attachments of the labor orce; and personal income. The general content of the tables in Chapter B and Chapter C is indicated in the charts on pp. viii ind ix.

Additional reports are also planned on such subjects as mobility of the population, characteristics of families and households, ativity and parentage, institutional population, characteristics of the nonwhite population by race, and characteristics of the labor orce. These special reports will relate mainly to the United States and regions. In some cases, a few tables for States and other large areas will also be included.

Statistics on the number of inhabitants as shown in Chapter A In this volume are all based on complete counts of the population. Similarly, the statistics on the general characteristics of the popuation presented in Chapter B are based on complete counts except in the case of those characteristics, such as school enrollment and income, that were reported for only 20 percent of the population. For Chapter C, only the tabulations relating to occupation and industry are based on complete counts; all the other tabulations are confined to the 20-percent sample. Because of sampling variability, differences may be expected between figures obtained from a complete count and the corresponding figures based on the 20-percent sample. Furthermore, differences between figures for corresponding items in different tables may arise because they were prepared from separate tabulations. The resources available did not permit a full adjustment of small processing differences, whereas in earlier censuses such adjustments were made.

In the Series P-A, P-B, and P-C bulletins, the tables were numbered in such a way as to provide a continuous series when bound together in this volume. Thus, tables 1 to 9 present data on the number of inhabitants for this State, tables 10 to 50 present the data on general characteristics of the population, and tables 51 to 94 present the data on detailed characteristics.

PUBLISHED DATA FOR NONWHITE POPULATION

In Chapter B, there are a number of tables for the South in which additional information on the characteristics of the nonwhite population is presented. These tables-28a, 30a, 32a, 37a, 45a, 48a, and 49a-present statistics on occupation, industry, income, and other subjects for the State and areas within the State. Most of the foreign-born white population is to be found outside the South. Tables 34a and 42a present statistics on country of birth of the foreign-born white in the North and West. These basic differences between the South and other regions are also recognized in tables 36, 38, 44, and 50 in which the content for Southern States is somewhat different from the content for the Northern and Western States.

In Chapter C, statistics for the nonwhite population are presented for all areas with a relatively large nonwhite population, regardless of the region in which they are located. Statistics on marital status, relationship to head of household, education, employment status, and occupation are presented by age for the nonwhite population for those States, standard metropolitan areas, and cities that had 50,000 or more nonwhite inhabitants in 1950. For Southern States, separate data on nonwhite persons are also presented for those urban, rural-nonfarm, and rural-farm parts of the State having 50,000 or more nonwhite inhabitants. (In most of the Northern and Western States, relatively few nonwhite persons live in rural areas.)

Selected statistics are also presented in Chapter C for the population classified by race (white, Negro, and other races) for all States and for standard metropolitan areas, and, in some cases, cities with a total population of 100,000 or more. These data include separate distributions by age, occupation, industry, and income.

AVAILABILITY OF UNPUBLISHED DATA

For urban places smaller than 10,000 inhabitants, and for the urban and rural parts of counties, only part of the tabulated data are published in Chapter B. A complete listing of tabulated, but unpublished, statistics for these areas is contained in the publication, U. S. Bureau of the Census, U. S. Censuses of Population and Housing: 1950, Key to Published and Tabulated Data for Small Areas, Washington, D. C., 1951.1

Some of the detailed statistics tabulated for large areas in connection with the preparation of Chapter C are not being published; for example, separate data for each standard metropolitan area and city of 100,000 or more, and certain statistics for the nonwhite population. A complete description of these unpublished data can be obtained upon request.

The tabulated, but unpublished, statistics can be made available upon request, for the cost of transcription or consolidation. If enumeration district data are desired, copies of maps showing enumeration district boundaries can also be furnished, usually at nominal cost. Requests for such unpublished material should be addressed to the Director, Bureau of the Census, Washington 25, D. C.
