Bibliographic Citation: Characteristics of Census Tracts in Nine U.S. Cities, 1940-1960 [machine readable data file]. Compiled by the U.S. Department of Commerce, Bureau of the Census. Edition prepared by David Elesh, Department of Sociology, University of Wisconsin. 1st DPLS 1971 Ed. Madison, WI: David Elesh, University of Wisconsin, Department of Sociology [producer], 1971. Madison, WI: University of Wisconsin, Data and Information Services Center [distributor], 1971, 1997 (26 data files).

Originating Organization or Researcher: David Elesh, Department of Sociology, University of Wisconsin.

Date of Study or Data Collection: 1960 data are available for all nine cities; 1940 and 1950 data are available for Detroit and Chicago only.

Universe to Which Data Pertain: Census tracts in Atlanta, Baltimore, Chicago, Cleveland, Detroit, Newark, New Orleans, Philadelphia, and Pittsburgh.

Sample Description: All census tracts in the central cities, except that a few tracts were omitted or combined with others in order to assure compatibility over time or because they were partly outside the central city.

Number of Data Units: Atlanta: 106 census tracts; Baltimore: 168 tracts; Cleveland: 205 tracts; Chicago: 809 tracts; Detroit: 451 tracts for 1940, 465 for 1950 and 1960; Newark: 100 tracts; New Orleans: 155 tracts; Philadelphia: 370 tracts; Pittsburgh: 189 tracts.

Reference Material: Codebooks supplied by David Elesh and complete printout.

Abstract: The 8 card images for each tract are divided into two files. Decks 1-4 are raw data on population (total, males, females, Negroes, foreign origin, Polish, Czech, Hungarian, Russian and Italian) age (median for white and nonwhite males and females; females 14 years and older; and number of persons older than 5 years, under 18 and over 25), family (number of married couples, married couples with own household, unrelated individuals, married females, separated females, married couples with own children under 18 and married women with husband present in labor force; and population per household), education (number of persons 25 and older who completed 1-3 years of high school, who graduated from high school, who completed 1-3 years of college and who are college graduates; and median years of school completed), income (base population for income data; number of persons with incomes $6000 to $6999, $7000 to $7999, $8000 to $8999, $9000 to $9999, $10,000 to $14,999, $15,000 to $24,999, and above $25,000; median family income; and percent with income less than $3000), housing (percent of housing units which are substandard, median rent, previous residence, and numbers of persons who lived in the South 5 years ago), and occupation (percent of male labor force which is unemployed, percent of male labor force in white collar occupations, total number of employed males, and number of males employed in nine specified occupations). Decks 5-8 repeat many of the raw variables transferred into percentage terms and include additional data on area of tract; latitude; longitude; and numbers of pharmacists, hospital beds, short-term hospitals, general hospitals, physicians over 70, total physicians, physicians who passed National Boards, general treatment physicians, pediatricians, specialists, and National Medical Association members. This data set complements other DPLS data sets dealing with hospitals and individual physicians.

Technical Notes: There are two data files per city per year. For a given year the data for each city is composed of eight decks that have been split into two files (decks 1-4 and decks 5-8). Decks 1-4 contain mainly raw data but also a few percentage variables; decks 5-8 include percentage transformations of the raw data, duplication of several raw data variables (mainly those used as bases for percentages), land use, hospital, and physician data. All percentages are carried to 1 decimal place and coded in a 3 column field such that the maximum value possible is "99.9%"--the decimal point was not punched. Data for tract numbers followed by "CV" in the 1960 tract reports represent statistics for "crews of certified vessels" and were not coded.

Descriptors: Census, tract, population, physicians, health care, income, occupation, demographics, race, hospitals, pharmacists, doctors.
