Table 2.

Sociodemographic Characteristics of Urban Population Within and Outside of a Retail Clinic Catchment Area

Based on Census data from 2000. This table focuses only on the urban population because the vast majority of retail clinics are located in urban areas. Retail clinic catchment areas were defined as those census blocks within a 5-minute driving distance around any clinic. Data provided as n (%), except for median household income.
* Insurance rates were obtained at the county level and then applied to the census tract.

This table focuses only on the urban population and defines retail clinic catchment area based on a 5-minute driving distance.
* We could not define 4 quartiles for these variables because of skew (a large number of census blocks with 0% nonwhite or Hispanic population). For the Hispanic percentage variable we divided the census blocks into 3 groups. For the nonwhite percentage variable we divided the census blocks into 4 groups, but the quartile 1 group had slightly more than a quarter of the census blocks whereas the quartile 2 group had slightly less than a quarter.
