Bank Density, Population Density, and Economic Deprivation Across the United States
Scott W. Hegerty

TL;DR
This study analyzes nationwide bank densities across U.S. Census tracts, examining how measurement radius and population density influence the identification of banking deserts and their association with economic deprivation.
Contribution
It provides a comprehensive nationwide analysis of bank densities using multiple measurement radii and links banking deserts to economic deprivation, extending previous city-specific studies.
Findings
Bank density varies significantly with measurement radius.
Lower thresholds effectively identify banking deserts.
Economic deprivation is higher in desert tracts, especially in dense urban areas.
Abstract
Recent research on the geographic locations of bank branches in the United States has identified thresholds below which a given area can be considered to be a "banking desert." Thus far, most analyses of the country as a whole have tended to focus on minimum distances from geographic areas to the nearest bank, while a recent density-based analysis focused only on the city of Chicago. As such, there is not yet a nationwide study of bank densities for the entire United States. This study calculates banks per square mile for U.S. Census tracts over ten different ranges of population density. One main finding is that bank density is sensitive to the measurement radius used (for example, density in urban areas can be calculated as the number of banks within two miles, while some rural areas require a 20-mile radius). This study then compiles a set of lower 5- and 10-percent thresholds that…
