The data files known as the Census Tract Data, 1950: Elizabeth Mullen Bogue File, were deposited with the National Archives and Records Administration (NARA) by a deed of gift from Dr. Donald Bogue of The Community and Family Study Center, University of Chicago. The 1950 Census Tract files were originally created by keypunching the data from the printed publications prepared by the Bureau of the Census. Record copies of these publications can be found in the Publication of the U.S. Government (Record Group 287). The 1950 census tract data reported in those publications were manually keypunched by The Community and Family Study Center, under the direction of Dr. Bogue. Much of this work was accomplished by Elizabeth Mullen Bogue, the wife of the principal investigator, Ms. Maggie Gibson, and a number of other students and staff. Related funding for this project (for analysis and student training) came from a number of sources including the National Science Foundation, National Institute of Child Health and Human Development, U.S. Agency for International Development, and the Social Science Division of the University of Chicago.

One of Dr. Bogues students, Dr. Michael White, obtained copies of the Census Tract Data files. Dr. White of the Population Studies and Training Center, Brown University, arranged for the transfer of these files to NARA on behalf of Dr. Bogue. The 1950 Census Tract Data came to NARA in November 1998, along with a copy of the original documentation.

The documentation indicates that the data were originally keypunched onto multiple punchcards for the city/metro area as a whole and for each tract. NARA received 59 files, one per available tracted city, with variable length records. There are two record types in each file; a ' city and metro level' record type with a record length of 2058 and a ' tract level record type with a record length of 1261. Dr. White confirmed that at some point in time the original 80 column records were concatenated into one long record per area. Note that the first eight bytes in each block/record is a binary block length/record counter. NARA prepared record layouts for each record type based on the original documentation and a review of the Census Tract publications for Austin, Texas. A copy of the Austin report is included as part of the technical documentation.

The first two records in each file are for the 'city and metro level data and the remainder of the records in the file contain 'tract level' data, arranged numerically by tract. Each file has two records at the beginning of each file; a 'metro level' record followed by a 'city level' record. When applicable, the 'metro level' record incorporates data tabulated for suburban tracts. In cities without suburban tracts, both a 'metro level' record and city level' record are included in the file, but the data are identical. The 'metro level' and 'city level' records are distinguished by the characters METR and CITY in columns '64-68 of the records.

Documentation for the 1950 Census Tract files consist of this introduction, NARA produced record layouts for the 'city and metro level' and 'tract level' record types, the original documentation for the keypunched files, and a NARA produced sample printout of records from the file for Austin, Texas, and a copy of the publication 'Census Tract Statistics, Austin, Texas'. The 'Census Tract Statistics, Austin, Texas' document includes a list of all tracted cities and indicates those that include surrounding suburban tracts as 'metro' areas. NARA did not receive from the donor, most significantly, files for Honolulu, New York, Los Angeles, San Francisco-Oakland, and Minneapolis-St. Paul. Apparently those census tract data were never converted to an electronic form.
A copy of a sample census tract publication is included so that the researcher can cross-check the data element titles and relationships between items presented in the original publication. In the process of preparing the NARA record layouts, NARA staff checked as closely as possible the data element titles and locations in the electronic records. Some discrepancies in the data values between the publication and the data file were noted, especially in calculated values (i.e. median income, median rent). Researchers should be aware that, because of the complexity involved in its preparation, there may be instances where the NARA prepared record layout may be in error. The donor could not supply a record layout that matched the current format of the data.

For researchers obtaining copies of these file converted to ASCII, please note that the first eight characters of each record (i.e. the block size/record length counter) will not be converted. Therefore, the actual record length and data element positions will be eight characters less than that indicated in the NARA prepared record layout. A general rule however is that, following the FILE/RECORD TITLE and NUMBER OF TRACTS fields in the 'city/metro area' records, each data element is eight characters in length. In the 'tract' level data, following the TRACT ID and TRACT SEQUENCE NUMBER fields, . each data element is five characters in length.

Record copies of all census tract publications can be found in the Publications of the U.S. Government (Record Group 287), or in various depository libraries across the United States. Among NARA's cartographic holdings are the original enumeration district maps, which also identify the tract areas for the tracted cities.

Subject : 1960 Census Tract Level Layout
To : File

Included as part of the technical documentation for the Census Tract Data, 1960: Elizabeth Mullen Bogue file is the original documentation provided with the data files at the time of deposit in the National Archives. Specifically, the documentation provided is the record layout for the tract level records in the data files. Note that the record layout does not account for the first eight bytes which are the embedded block size/RECORD LENGTH COUNTER. Therefore, researchers using the tract level record layout should add eight bytes to the positions indicated in the record layout to identify the exact location of any particular data element. Therefore, the actual length of the tract level records is 2742 bytes; eight bytes longer than that indicated in the original documentation. NARA prepared a layout for the SMSA/CENTRAL CITY record layout based on the listing of data elements presented in the census tract level layout.
