This article evaluates the spatial relationship between primary care provider clinics and walk-in clinics. Using ZIP code level data from Harris County, Texas, the results suggest that primary care physicians and walk-in clinics are similarly located at lower rates in geographic areas with populations of lower socioeconomic status. Although current clinic location choices effectively broaden the gap in primary care access for the lower income population, the growing number of newly insured individuals may make it increasingly attractive for walk-in clinics to locate in geographic areas with populations of lower socioeconomic status and less competition from primary care physicians.
