Description: {"definition": "Percentage of housing units in a county without a car and more than 1 mile from a supermarket or large grocery store.", "availableYears": "2010", "name": "Households, no car & low access to store (%), 2010", "units": "Percent", "shortName": "PCT_LACCESS_HHNV10", "geographicLevel": "County", "dataSources": "Data are from the 2017 report, Low-Income and Low-Supermarket-Access Census Tracts, 2010-2015 and the 2012 report, Access to Affordable and Nutritious Food: Updated Estimates of Distances to Supermarkets Using 2010 Data. In each of these reports, a directory of supermarkets and large grocery stores authorized to accept SNAP benefits was merged with Trade Dimensions' TDLinx directory of stores within the United States, including Alaska and Hawaii, for the years 2010 and 2015. Stores met the definition of a supermarket or large grocery store if they reported at least $2 million in annual sales and contained all the major food departments found in a traditional supermarket, including fresh meat and poultry, dairy, dry and packaged foods, and frozen foods. The combined list of supermarkets and large grocery stores was converted into a GIS-usable format by geocoding the street address into store locations. Data on 2010 households are drawn at the block group-level from the 2006-10 American Community Survey, and data on 2015 households are drawn at the block group-level from the 2010-14 American Community Survey. These data were first allocated to blocks and then aerially allocated down to 1/2-kilometer-square grids across the United States. For each 1/2-kilometer-square grid cell, the distance was calculated from its geographic center to the center of the grid cell with the nearest supermarket. Vehicle access was measured based on an American Community Survey question that asks respondents if the household has access to a car, truck or van, of 1-ton capacity or less. Once distance to the nearest supermarket or large grocery store was calculated for each grid cell, the number of housing units more than 1 mile from the nearest supermarket or large grocery store was aggregated to the county level. That number was divided by the total number of housing units in the county to obtain the percentage of housing units in the county that were more than 1 mile from a supermarket and without a vehicle."}
