ZIP 99203 in context

How this area compares with national benchmarks.

ZIP 99203 is a mid-size town in Spokane County, Washington, with 21,921 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #163 of 605 ranked by population — larger than 73% of them. The median age here is 42.8 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 99203 earn a median of $95,532 a year, 21.6% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 5.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 99203 is valued at $449,100, 48% above the national figure, while median gross rent runs $1,243 a month, 11.6% below the national figure, or roughly $14,916 across a full year. A household on the local median income would put about 15.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 4.7×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 76.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.

Reading ZIP 99203 in context

How 99203 sits inside Spokane County and Washington.

ZIP 99203 is tabulated inside Spokane County, Washington, one of 40 ZIP areas the Census publishes for that county and 605 across Washington. This is a mid-sized suburban ZIP inside a county that is split across many delivery areas. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 99203 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 99203 reports a median household income of $95,532, 29% above the $74,302 county median, and 18% above the $80,861 typical WA ZIP. Owner-occupied homes are valued at a median of $449,100, 22% above the county figure and 7% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,243 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 99203 carries 9% at the register, assembled from the Spokane jurisdiction stack: the Washington state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 99203 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 99203 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.

A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
