Click on color-coded areas to view one-page appraisals of Hartford-area neighborhoods by the Home Owners' Loan Corporation (HOLC) field agent in 1937. Agents rated not only the physical property but also the "social status of the population," and downgraded neighborhoods with Black, immigrant, and lower-income residents. Decades later, activists labeled these "redlining" maps, and while they reflect racist and elitist views, HOLC did not actually use them to deny mortgages. Map developed by Ilya Ilyankou and Jack Dougherty, based on an earlier versions created with UConn MAGIC and the Kirwin Institute. View historical sources and code on GitHub.
