Federal Disaster Declarations

FEMA declares disasters at the county level; counts here include every federally declared disaster touching any county that overlaps this ZIP.

Air quality

Based on Canyon County data (2024).

Community health profile

Low birth weight (under 2,500 g) accounts for 6.9% of live births in this county — an early-life health input that downstream outcomes track against.

Based on Canyon data (2025 CHR release).

Source: County Health Rankings & Roadmaps, University of Wisconsin Population Health Institute (countyhealthrankings.org). Annual release. Underlying source datasets vary by measure (CDC BRFSS, NCHS Vital Statistics, AHA, USDA Food Environment Atlas, and others). Figures are county-level and assigned to every ZIP whose primary county matches.

Food access

Among low-income residents, 7.4% are low-access — those without a supermarket within 1 mile (urban) or 10 miles (rural).

Per-1,000 figures show how many of each store type exist in Canyon County, ID for every 1,000 residents. Higher grocery and supercenter density usually means easier access to fresh food; higher convenience-store-only density (with low grocery rate) often signals a food swamp.

Source: USDA Economic Research Service, Food Environment Atlas (ers.usda.gov). County-level metrics fanned to ZIP via the primary county in the Census ZCTA-county relationship file. Variable years differ per family (stores ~2020, low-access ~2019).

Incoming households reported an average AGI of $65,426 versus departing households' $56,543.
