Areas of Limited Food Access represent living units in Denver that are more than a 10 minute walk to a full-service grocery store. The 10-minute walk walksheds were developed along the Denver Sidewalk Network at a walking speed of 4 Miles per hour. This is different than the previous measure of food access in Denver, which was based on a 1/4 mile distance from a full-service grocery store, as the crow flies (i.e. only based on distance not on where walking is actually possible). Full service grocery store is defined based on the size of the store and availability of healthy food options such as produce.Methods for estimating food access by neighborhood were updated in 2021 in partnership with the Department of Community Planning and Development. The updated method estimates neighborhood access based on living units within the 10 minute walkshed rather than using the proportion of the total neighborhood population within the walkshed, which better account s for where people actually live within a neighborhood.
