The Home Owners’ Loan Corporation (HOLC) was established in 1933 as a federal government-sponsored program. San Antonio was one of the cities for which "residential security maps" were created.

This site juxtaposes maps from the 1930s with contemporary health disparities to illustrate the long-lasting impact of racial segregation and redlining in shaping the enduring contours of marked inequality. Compares HOLC redlining maps from the1930s with maps showing the Center for Disease Control's Social Vulnerability Index (SVI) scores for census tracts of 200 cities today. A collaboration between the University of Richmond's Digital Scholarship Lab and the National Community Reinvestment Coalition.
