This data collection includes housing data by census tract for San Diego County in 1970. Sample counts (5%, 15% and 20%) are derived from the Census of Population and Housing, 1970: Summary Tape File 4A: Housing. Housing characteristics include housing value, number of housing units in structure, number of rooms in housing unit, year structure was built, occupancy/vacancy status, tenure, rent, type of heating fuel, source of water, and presence of an air conditioner and other home appliances. Counts are available for the total, Negro, and Spanish American populations. Negros are defined as a racial category by the Census Bureau. In California, Spanish Americans include "Persons of Spanish language or Spanish surname". The California state 4A data file was processed with PERL and SPSS by the Social Science Data Collection (SSDC) staff of the University of California, San Diego Library from Census Bureau data processed by DUALabs, Inc. and archived at the Odum Institute. PERL script concatenated record type codes and output six data files that match the record types described in the codebook: tables 001-040, tables 041-107, tables 108-119, tables 120-130, tables 131-152 and Spanish American tables 153-200. These six files were subsequently processed with SPSS to extract tracts for San Diego County and recompute some aggregate housing value data content. Users may browse a list of data variables (tables and cells) included in these six data files. The Census Bureau produced printed reports for 1970 Summary Tape File 4A. The UCSD Geisel Library maintains printed reports and census tract maps in 1970 Census of Population and Housing Census Tracts, San Diego, Calif. (SSH Docs US Stacks C 3.223/11:970/188).

METHODOLOGY NOTES (across all datasets for this indicator) All legal boundaries and names for Census geography (metropolitan statistical area, county, city, and tract) are as of January 1, 2010, released beginning November 30, 2010, by the U.S. Census Bureau. A Priority Development Area (PDA) is a locally-designated area with frequent transit service, where a jurisdiction has decided to concentrate most of its housing and jobs growth for development in the foreseeable future. PDA boundaries are current as of August 2019. For more information on PDA designation see http://gis.abag.ca.gov/website/PDAShowcase/.

Population estimates for Bay Area counties and cities are from the California Department of Finance, which are as of January 1st of each year. Population estimates for non-Bay Area regions are from the U.S. Census Bureau. Decennial Census years reflect population as of April 1st of each year whereas population estimates for intercensal estimates are as of July 1st of each year. Population estimates for Bay Area tracts are from the decennial Census (1970 -2010) and the American Community Survey (2008-2012 5-year rolling average; 2010-2014 5-year rolling average; 2013-2017 5-year rolling average). Estimates of population density for tracts use gross acres as the denominator.

Population estimates for Bay Area PDAs are from the decennial Census (1970 - 2010) and the American Community Survey (2006-2010 5 year rolling average; 2010-2014 5-year rolling average; 2013-2017 5-year rolling average). Population estimates for PDAs are derived from Census population counts at the tract level for 1970-1990 and at the block group level for 2000-2017. Population from either tracts or block groups are allocated to a PDA using an area ratio. For example, if a quarter of a Census block group lies with in a PDA, a quarter of its population will be allocated to that PDA. Tract-to-PDA and block group-to-PDA area ratios are calculated using gross acres. Estimates of population density for PDAs use gross acres as the denominator.

Annual population estimates for metropolitan areas outside the Bay Area are from the Census and are benchmarked to each decennial Census. The annual estimates in the 1990s were not updated to match the 2000 benchmark.

METHODOLOGY NOTES (across all datasets for this indicator)
All historical data reported for Census geographies (metropolitan areas, county, city and tract) use current legal boundaries and names. A Priority Development Area (PDA) is a locally-designated area with frequent transit service, where a jurisdiction has decided to concentrate most of its housing and jobs growth for development in the foreseeable future. PDA boundaries are current as of December 2022.

Population estimates for Bay Area counties and cities are from the California Department of Finance, which are as of January 1st of each year. Population estimates for non-Bay Area regions are from the U.S. Census Bureau. Decennial Census years reflect population as of April 1st of each year whereas population estimates for intercensal estimates are as of July 1st of each year. Population estimates for Bay Area tracts are from the decennial Census (1970-2020) and the American Community Survey (2011-2021 5-year rolling average). Estimates of population density for tracts use gross acres as the denominator.

Population estimates for Bay Area tracts and PDAs are from the decennial Census (1970-2020) and the American Community Survey (2011-2021 5-year rolling average). Population estimates for PDAs are allocated from tract-level Census population counts using an area ratio. For example, if a quarter of a Census tract lies with in a PDA, a quarter of its population will be allocated to that PDA. Estimates of population density for PDAs use gross acres as the denominator. Note that the population densities between PDAs reported in previous iterations of Vital Signs are mostly not comparable due to minor differences and an updated set of PDAs (previous iterations reported Plan Bay Area 2040 PDAs, whereas current iterations report Plan Bay Area 2050 PDAs).

This data collection is a block group subset of the Census of Population and Housing, 1970: Summary Tape File 1A for San Diego County, California. Block group complete count (100% long form) tabulations are available in 55 population and housing tables. Population tables include tabulations by total population, age, sex, race, marital status, relationship to household head, family type, and combinations of these. Housing tables include tabulations by housing units by number of rooms, persons per room, number of units with basement, value of owner occupied units, contract rent, plumbing facilities, and crowded units by type of household. A list of all table cell counts (variables) is available for these data tabulations. The San Diego block group data file was extracted and processed by the Social Science Data Collection (SSDC) staff of the University of California, San Diego from Census Bureau data processed by DUALabs, Inc. and archived at the Odum Institute. All counts in 1970 Summary Tape File 1A are considered final. 1970 Summary Tape File 1A is also known as 1970 Summary Statistics File 1A, and 1970 File A First Count Tallies: Block Groups and Enumeration Districts. The Census Bureau did not produce printed reports for 1970 Summary Tape File 1A. The UCSD Geisel Library maintains two copies of printed block maps in Block Statistics: San Diego, Calif. Urbanized Area (SSH Docs US Stacks C 3.224/5:970/23). Block groups can be identified by the first digit of the block number used in the maps. Block group "1" will contain any block numbered 101-199, block group "2" will contain any block number 201-299, and etc.
