Fresh.Data current as of Apr 24, 2026
Country Homes, WA (ZIP 99251) sits in Spokane County within the Spokane-Spokane Valley metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: High Blood Pressure comes in below the national average at 7.4%. 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 $14,784. Local establishments report average pay of $25,572 per worker (Census ZBP) — below the US average. Social vulnerability is low in this ZIP at the 24th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. FEMA has issued 28 federal disaster declarations affecting this ZIP since 1964 — a high-frequency exposure profile. Fast-food restaurants outnumber grocery stores roughly 4-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. Washington has no state income tax (Tax Foundation 2025). New residents arriving here predominantly come from Kootenai County, ID (IRS SOI Migration, 2022-2023). Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: fair market rent of $1,440 for a two-bedroom and 27.4% 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
Country Homes, WA (ZIP 99251) sits in Spokane County within the Spokane-Spokane Valley metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: High Blood Pressure comes in below the national average at 7.4%. 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 $14,784. Local establishments report average pay of $25,572 per worker (Census ZBP) — below the US average. Social vulnerability is low in this ZIP at the 24th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. FEMA has issued 28 federal disaster declarations affecting this ZIP since 1964 — a high-frequency exposure profile. Fast-food restaurants outnumber grocery stores roughly 4-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. Washington has no state income tax (Tax Foundation 2025). New residents arriving here predominantly come from Kootenai County, ID (IRS SOI Migration, 2022-2023). Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: fair market rent of $1,440 for a two-bedroom and 27.4% 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.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
One concrete reading worth keeping: Depression prevalence sits higher the national rate at 32.7%. 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.
