Westchester County, NY

The USDA Economic Research Service Food Access Research Atlas flags 114 of Westchester County's 249 census tracts as low-access, covering 365,233 residents of a 998K total population. That translates to a county-wide low food access share of 36.6%, which measures how many people live more than one mile from the nearest supermarket in urban settings or more than ten miles in rural settings. Because New York classifies tracts using the same distance thresholds the USDA applies nationwide, Westchester County's figure is directly comparable to peer counties and to the state benchmark.

The food desert signal strengthens when distance is stacked with income. In Westchester County, 82,116 residents are flagged as low-income and more than one mile from a supermarket (the urban threshold), while 27,372 meet the low-income, ten-mile rural threshold. Those overlapping conditions are the precise combination the USDA uses to designate a food desert tract. Layered context includes a median household income of $114,651, a poverty rate of 8.5%, and SNAP participation covering 33,708 households — roughly 9.2% of the county — drawn from the Census Bureau American Community Survey five-year estimates.

Transportation is the hidden variable behind most food access gaps. About 14.2% of Westchester County households report no vehicle available, meaning any measured distance to a supermarket translates into a real trip on foot, by transit, or by asking for a ride. Group quarters residents — 2.5% of the population — are counted separately because their food access patterns follow an institution rather than a household. With more than 30% of Westchester County in a low-access area, the county sits well above the national median and warrants closer review of supermarket siting, SNAP outreach, and transit connections.
