Marion County · Salem, OR · Population 172
Fresh.Data current as of Apr 24, 2026
OR 97373 (ZIP 97373) sits in Marion County within the Salem metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Annual Checkup comes in above the national average at 61.6%. No NCES schools are mapped to this ZIP in the current dataset. 10 colleges and universities serve the area, with median in-state tuition of $13,140. CDC's Social Vulnerability Index places this ZIP in the 98th percentile nationally — a highly vulnerable community profile. FEMA has issued 15 federal disaster declarations affecting this ZIP since 1964. 22% of adults self-report fair or poor health (County Health Rankings, 2025) — above the national county median. Fast-food restaurants outnumber grocery stores roughly 6-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. New residents arriving here predominantly come from Polk County, OR (IRS SOI Migration, 2022-2023). Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: fair market rent of $1,390 for a two-bedroom, a 71.6% poverty rate (well above the ~12% US average), and 87.5% of workers working from home. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

What these numbers say together
OR 97373 (ZIP 97373) sits in Marion County within the Salem metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Annual Checkup comes in above the national average at 61.6%. No NCES schools are mapped to this ZIP in the current dataset. 10 colleges and universities serve the area, with median in-state tuition of $13,140. CDC's Social Vulnerability Index places this ZIP in the 98th percentile nationally — a highly vulnerable community profile. FEMA has issued 15 federal disaster declarations affecting this ZIP since 1964. 22% of adults self-report fair or poor health (County Health Rankings, 2025) — above the national county median. Fast-food restaurants outnumber grocery stores roughly 6-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. New residents arriving here predominantly come from Polk County, OR (IRS SOI Migration, 2022-2023). Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: fair market rent of $1,390 for a two-bedroom, a 71.6% poverty rate (well above the ~12% US average), and 87.5% of workers working from home. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
Both surfaces skew lighter than national averages. That isn’t a verdict — small-area estimates compress real neighborhood-level texture, and a single ZIP reading can miss a district line or a hospital corridor sitting just outside it. Treat this as a starting point for fieldwork, not a conclusion.
One concrete reading worth keeping: Depression prevalence sits near the national rate at 23.5%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.

The Social Vulnerability Index uses U.S. Census data to identify communities most at risk during public health emergencies and natural disasters. Higher percentiles indicate greater vulnerability. Tract-level scores are aggregated to this ZCTA via Census 2020 ZCTA→Tract crosswalk, weighted by land-area share. Source: atsdr.cdc.gov. Public domain.
