Racial discrimination by housing and lending institutions occurs worldwide. In the United States, it was legal and widely practiced well into the 1960s and has persisted in varying forms since. The Home Owner's Loan Corporation (HOLC) was one of many institutions engaging in racially discriminatory practices and created neighborhood appraisal maps in the 1930s based in part on race, ethnicity, and economic class of a neighborhood's residents. Using these HOLC neighborhood boundaries, we compared 12 present day population characteristics including health, employment, education, and income measures in each of the four HOLC neighborhood ratings across 14 U.S. cities. We used population-weighted logistic regression for paired data comparison and unsupervised learning techniques to uncover the consistency between HOLC evaluations and today's socio-economic and health outcomes. While existing literature focuses on case studies of particular cities and outcomes, we took a broad view and found consistent relationships over our study's cities and variables with few exceptions. Though there are many factors that contribute to continued inequality in a particular area, this study demonstrates that socio-economic and health inequality measured across numerous indicators continues to align with historic discriminatory housing boundaries.

住房和贷款机构的种族歧视在世界范围内发生。在美国，这是合法的，并且在1960年代得到了广泛的实践，并且从那以后一直以各种形式存在。房主贷款公司（HOLC）是从事种族歧视做法并在1930年代创建的，部分基于邻里居民的种族，族裔和经济阶层的邻里评估地图的众多机构之一。使用这些HOLC社区边界，我们在美国14个城市的四个HOLC社区等级中，比较了12个当今的人口特征，包括健康，就业，教育和收入指标。我们使用人口加权Logistic回归进行配对数据比较和无监督学习技术，以发现HOLC评估与当今的评估之间的一致性。社会经济和健康状况。尽管现有文献着重于对特定城市和结果的案例研究，但我们采取了广阔的视野，发现我们研究的城市和变量之间存在一致的关系，只有少数例外。尽管有许多因素导致特定地区持续的不平等现象，但这项研究表明，在众多指标上测得的社会经济和健康不平等现象仍与历史性的歧视性住房界限保持一致。
