Alex Ramiller

I am a Ph.D. Candidate in City and Regional Planning at the University of California, Berkeley, and researcher at the Terner Center for Housing Innovation. My current research focuses on the use of large administrative datasets to study the relationships between residential mobility, neighborhood change, and urban form. I have previously conducted work on topics ranging from the impact of building renovations and demolitions on eviction risk to the politics of urban sustainability in Denmark. My work has been published in journals including Urban Studies, Housing Studies, Urban Environment, and Cityscape. I have authored reports for organizations including the U.S. Department of Housing and Urban Development (HUD) and the Federal Reserve Bank of San Francisco.

I have also provided data science consulting on a range of reports and dashboards related to housing policy and urban planning, including playing a leading role in the development of dashboards tracking post-pandemic rent debt and residential displacement risk in Seattle. I am currently working on projects related to the landscape of multifamily homeownership in the United States and the pursuit of Affirmatively Furthering Fair Housing (AFFH) in California.

Dashboards

Rent Debt in America

This dashboard and accompanying analysis use experimental Census survey data to measure the ongoing impact of the Covid-19 pandemic on household rent debt. Rent debt estimates are provided for states, counties, and cities throughout the United States. This dashboard was created for PolicyLink as part of the National Equity Atlas.

Tracking California's Rent Relief

This dashboard and accompanying anslysis use administrative data from the California Covid-19 Rent Relief Program to track the status of rent relief applications. This project was created for PolicyLink as part of the National Equity Atlas.

Housing Precarity Risk Model

The Housing Precarity Risk Model (HPRM) provided a national analysis of housing precarity, identifying vulnerable neighborhoods that were in particularly urgent need of assistance and resources from local, state, and federal agencies, particularly in the wake of the Covid-19 pandemic. The project was created for the Urban Displacement Project.

Seattle Displacement Risk Indicators

This dashboard brings together demographic and market data to construct dynamic indicators of displacement risk across Seattle neighborhoods. The dashboard was constructed for the City of Seattle Office of Planning and Community Development's Equitable Development Monitoring Program.
