Community, Diversity, and Displacement Study

Housing banner

This study seeks to better understand the displacement vulnerability of San Joaquin County households. Through the development of a customized mapping tool, interested stakeholders can better understand what neighborhoods face the greatest displacement risk as well as what portions of the county have tipped into “exclusionary” territory – where housing prices have increased to the point that vulnerable households are effectively priced out. In addition, this report recommends four strategies that the San Joaquin Council of Governments can take to begin ensuring that its own investment practices help to support neighborhood housing stability while creating local community benefits -- and don’t inadvertently contribute to or directly cause residential displacement.

Condensed Typology

Description Original UDP Typology
Susceptible to and Ongoing Displacement These tracts are low or mixed low-income and some had an absolute loss of low-income households during the period of 2000-2018 Low Income/Susceptible to Displacement; Ongoing Displacement of Low-Income Households
Varying Levels of Gentrification These tracts have varying levels of income and housing affordability, and some tracts gentrified during 1990-2000 or 2000-2018, but all tracts have experienced an increase in housing costs and/or rental value during the 2012-2018 period.  At Risk of Gentrification; Early Ongoing Gentrification; Advanced Gentrification
Moderate and Mixed Incoming Moderate- and Mixed- Income These tracts range from moderate to high income and other variables are relatively stable. Stable Moderate/Mixed Income Stable Moderate/Mixed Income
Varying Levels of Exclusiveness These tracts range from moderate to high income and housing costs are increasing. In some tracts, low-income households are being excluded from entering and decreasing in numbers. At Risk of Becoming Exclusive; Becoming Exclusive; Stable/Advanced Exclusive
High Student Population These tracts have a high percentage of college students (over 30%) and therefore were excluded from the analysis.  High Student Population

*Income levels relate to regional area median income (AMI). For the San Joaquin County model, AMI is equivalent to the MHI for San Joaquin County, $55,167 (data source, 5-year 2014-2018 ACS data). Low Income = AMI <80% Moderate Income = AMI 80-120% High Income = AMI > 120%
