SAVI Community Trends Report: Unequal Access Tobacco Epidemic Report 2017 FINAL - Page 6

SAVI community trends » unequal access: tobacco retail in the indianapolis metro area To measure density, we included both retailer density and network density, which accounts for an individual’s ability to walk or drive to a nearby retailer. Retailer accessibility differs from network density in that it examines the proportion of the tract area within 500 meters (approximately 1/3 mile) – considered a walk- able distance. [25, 48-50] The objective of calculating this metric was to identify the tracts where an individual may be exposed more often to the presence of tobacco retailers (and, potentially, tobacco marketing). We calculated the access score and then clustered census tracts into groupings for further analysis. We grouped tracts based on Jenks calculations, which maximize variation between groups while minimizing variation within groups, using the following score ranges: Low access tracts (scores ranged from 0.10 – 8.53, n=229); Medium access tracts (8.80– 22.42, n=112); High access tracts (22.66 – 43.27, n=56). All charts and maps were produced by The Polis Center at Indiana University Purdue University Indianapolis, March 2017.
