Structural racism in the form of contemporary and historical residential segregation have been linked to the persistence of many racial/ethnic health disparities within the United States. Contemporary residential segregation measures used in current research ignore the impact of historical residential segregation, which is likely to have influenced present day racial residential segregation. We propose a new segregation measure that combines the prior information of the historical context defined by Home Owners Loan Corporation designations along with the contemporary residential segregation landscape for a given neighborhood. We further examine its impact on hypertension prevalence among three different cities using data from PLACES and the ACS 5-year estimates. Utilizing Bayesian spatial methods, we assessed if our new measure explains additional variation in hypertension prevalence at the census tract level, then what contemporary or historical residential segregation already explain separately. The purpose of our new measure is to provide a way of determining the degree of influence that historical residential segregation may have on contemporary residential segregation.
