Washington Parish, LA

The USDA Economic Research Service Food Access Research Atlas flags 10 of Washington Parish's 11 census tracts as low-access, covering 34,044 residents of a 46K total population. That translates to a county-wide low food access share of 74.8%, 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 Louisiana classifies tracts using the same distance thresholds the USDA applies nationwide, Washington Parish'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 Washington Parish, 6,827 residents are flagged as low-income and more than one mile from a supermarket (the urban threshold), while 2,276 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 $41,803, a poverty rate of 23.5%, and SNAP participation covering 4,467 households — roughly 26.0% 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 10.1% of Washington Parish 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 — 3.7% of the population — are counted separately because their food access patterns follow an institution rather than a household. With more than 30% of Washington Parish 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.
