There are significant disparities in geographic access to asthma care within states
In Georgia, the distances to asthma specialist care (averaged at the county level) range from 2 to 50 miles, with a standard deviation within-county as high as 26 miles. Of the 159 counties in Georgia, 23 have an average travel distance greater than 30 miles. In contrast, in NC, the maximum distance to specialist care is 30 miles, with only 4 of 100 counties with an average distance over 15 miles. Travel distances to primary care are generally lower than to specialist care; however, they also vary greatly within the two states.
