Overcrowded Housing

This feature data depicts, by census tract, the overcrowding status of owner and renter occupied housing units for the San Francisco Bay Region. The source data used to produce this data layer is Table 10 of the Comprehensive Housing Affordability Strategy (CHAS) data produced by the United States Department of Housing and Urban Development (HUD) and released on September 29, 2021. HUD used 2014-2018 American Community Survey (ACS 2018) data to update its 2006-2017 CHAS data. The Metropolitan Transportation Commission (MTC) made a number of changes to the source data to produce this feature set. To produce this feature set, the MTC joined the source table to a Census 2010 tract polygon feature set. The joined feature set was then exported to create a feature set representing the average number of persons per room for owner and renter housing units in the San Francisco Bay Region. The resulting attribute table had all fields from the source table that were not needed deleted and the remaining field names were changed. In addition, MTC added the jurisdiction (incorporated city/town or unincorporated county) name the tract is within. Percent fields were also added for each owner and renter column that provide the source field's percent of all housing units for the tract. The source table used to develop this feature service was downloaded from https://www.huduser.gov/portal/datasets/cp.html#2006-2017_data About the CHAS Each year, HUD receives custom tabulations of ACS data from the United States Census Bureau. These data, known as the "CHAS" data, demonstrate the extent of housing problems and housing needs, particularly for low income households. The CHAS data are used by local governments to plan how to spend HUD funds, and may also be used by HUD to distribute grant funds.

HUD definitions for overcrowding: ● Overcrowded - More than 1 person per room ● Severely overcrowded - More than 1.5 persons per room
