STUDY DESCRIPTION: San Diego County was partially tracted by the Census Bureau in 1950. This data collection contains 1950 Census Tract subject counts (variables) for San Diego City and adjacent areas. The 1950 census tract file data file was originally created by keypunching most of the subject counts from tables 1-3 in the Census Bureau printed publication, "Census of population: 1950, Vol.III, Census Tract Statistics, Chapter 48" [San Diego, Calif.]. The work was done under the direction of Dr. Donald Bogue, whose wife, Elizabeth Mullen Bogue, completed much of the data work. Subsequently, the punchcards were converted to data files and transferred to the National Archive and Records Administration (NARA). ICPSR received copies of these files from NARA and converted the binary block-length records to ASCII format. This San Diego, California 1950 census tract data file was reformatted and modified by the Social Science Data Collection (SSDC) staff of the University of California, San Diego. The original codebook for this data collection is freely available from ICPSR in PDF format (ICPSR 2931, DATASET 60).

EXTENT OF COLLECTION: documentation + data file.

• CODEBOOK (PDF): The SSDC staff created a PDF codebook, Census Tract-Level Data, 1950: San Diego, CA that documents these data.

• NOTES AND ERRATA (HTML): The differences between the data tables in the printed Census Bureau publication, the Bogue data file and the SSDC version of the Bogue data file.

The file contains all of the variable names and column locations in the data file and can be edited by users of statistical software to create syntax files.

• DATA FILE (Excel): SSDC version of the Bogue data.

• DATA FILE (ASCII): The format of the SSDC ASCII data file follows:
