Food Insecurity in Past 12 Months (Percent of Adults) |
FOODINSECU_CrudePrev |
Modeled crude prevalence (percent) of adults reporting food insecurity in the past 12 months. | Adults 18+; released by CDC PLACES for census tract and ZCTA geographies. | CDC PLACES measure definitions |
total_population |
B01003_001E |
Total population estimate used to convert prevalence rates into estimated counts of affected residents. | All people; ACS 5-year estimates (tract and/or ZCTA, depending on output table). | ACS table B01003 metadata |
pct_within_1mi_of_food_pantry |
Derived (pantry points + Census geography) | Percent of tract or ZCTA land area that falls within a 1-mile buffer of at least one mapped pantry point. | Census tract or ZCTA polygons intersected with pantry-service buffers. | Methods: coverage construction |
estimated_food_insecure_people |
total_population * (food_insecurity_pct / 100) |
Estimated number of food-insecure residents in each geography after scaling CDC prevalence by population. | Computed for each tract/ZCTA where population and food-insecurity prevalence are available. | Methods: need estimate formula |
estimated_uncovered_food_insecure_people |
estimated_food_insecure_people * (1 - coverage_share) |
Estimated number of food-insecure residents outside modeled 1-mile pantry coverage. | Computed tract-by-tract or ZCTA-by-ZCTA from modeled need and coverage. | Methods: uncovered-need formula |
Food Pantry Desert Index |
Derived | Statewide 0-100 relative index of pantry access pressure based on modeled need and modeled geographic coverage. | Published separately for tract and ZCTA views as a relative planning signal. | Methods: index construction and scaling |
