The Redlining Lab is Kate Thomas (NYU), Thomas Storrs (University of Virginia), Wenfei Xu (UCSB), and Jacob Faber (NYU).
By linking historical Home Owners' Loan Corporation (HOLC) appraisal maps from the 1930s and 1940s to contemporary data on race, wealth, health, and opportunity, the lab investigates how mortgage discrimination inscribed in these maps continues to shape the geography of inequality in American cities.
The Redlining Lab is funded by the Russell Sage Foundation, the Washington Center for Equitable Growth, and the NYU Institute of Human Development and Social Change.

New-deal mortgage programmes benefited white borrowers disproportionately
Thomas, K., Storrs, T., Xu, W., Faber, J.
Nature, 2026
We show that the Federal Housing Administration (FHA) and Veterans' Administration (VA) mortgage programmes had few Black borrowers and proportionate foreign-born borrowers in their early years. Although scholars have long posited that the beneficiaries of these programmes were disproportionately white, evidence of the identities of these early borrowers was scant and lacking information on their nativity.
Here we fill this void by linking records from the Reconstruction Finance Corporation Mortgage Company (RFCMC), consisting of 29,921 FHA-insured and VA-guaranteed loans from 1935 to 1947, to Census data.
Although the population of the USA was 9.9% Black in 1940, we find that only 2.1% of FHA-insured loans and 5.1% of VA-guaranteed loans went to Black borrowers. We also show that immigrants were proportionally represented in FHA lending (10.0% of loans) relative to their share of the population and in VA lending (2.2% of loans) relative to their share of Second World War veterans.
Our results indicate substantial racial inequality in the two foundational homeownership policies in the USA. We anticipate our findings to be a starting point for nascent scholarship exploring the roles of FHA and VA lending in shaping racial disparities in access to homeownership and related outcomes, such as neighbourhood attainment and wealth.
