Center for Data Visualization – Mapping the Origins of Redlining the United States

“A team of professors and students from the University of Richmond, the University of Maryland, Johns Hopkins University, and the Virginia Polytechnic Institute have created a data visualization called Mapping Inequality that combines 150 interactive maps of cities in the United States illustrating the racial demographic breakdown of homeowners between 1935 and 1940. The maps originally come from the Home Owner’s Loan Corporation (HOLC), a government agency established by the New Deal that scored neighborhoods for creditworthiness based on risk, a practice known as redlining which was responsible for widespread racial housing segregation. Mapping Inequality allows users to search for maps of cities and observe how the racial makeup of neighborhoods changed from before HOLC’s redlining, in 1930, to after, in 1940. Take a look.”
