Poor housing quality leads to poor health outcomes for renters in the City of Oakland, and the inequitable way in which this issue affects communities tends to be reflective of structural racism. Currently, the City of Oakland primarily responds to this issue via citizen complaints about housing habitability. It is likely that certain areas complain less about housing habitability due to a variety of factors, such as fear with respect to immigration status, language access, comfort with accessing city services, fear of landlord retribution, and other structural inequalities that prevent access. The City is working on a proactive enforcement system to provide equitable services but lacks a firm grounding in data.

- What is the relationship between housing quality and structural racism in Oakland? More specifically:
- What are the different characteristics of census tracts with low and high levels of housing habitability complaints? Are complaints most related to building characteristics or are race/ethnicity and other socioeconomic factors more significant? Relevant data: race/ethnicity, income, rent burden, primary language spoken at home, poverty, overcrowding, building type, “legal units”
For context, the Alameda County Department of Public Health has asked for an analysis of the types of housing that have the most housing habitability complaints (i.e. number of units in building, age of building, and location of building) to improve program design and advocacy for a new inspection program. Our hypothesis is that neighborhoods where there are large Latinx populations have disproportionately lower levels of housing habitability complaints compared to places with similar building types. People who are most likely to be impacted by housing habitability issues are often less likely to complain.

- Descriptive Analysis of where complaints come from building typology, building age, tract, neighborhood.
- How many complaints per census tract? Is this explained by building typology and age?
- Does each census tract have the number of complaints you would expect? Determine analytically whether one can sufficiently explain the variance in housing habitability complaints with only building-specific data. If structural racism & inequality is not playing a role, we would expect a proportionate amount of complaints across tracts given relevant housing stock (e.g. older buildings, high-unit density, etc.) If not, what are the demographic/socioeconomic factors from the ACS that help explain lower or higher than expected levels of complaints?
