ZIP 98831 in context

How this area compares with national benchmarks.

ZIP 98831 is a small town in Chelan County, Washington, with 4,020 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #314 of 605 ranked by population — larger than 48% of them. The median age here is 46.2 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 98831 earn a median of $73,223 a year, 6.8% below the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 6.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 98831 is valued at $652,300, 115% above the national figure, while median gross rent runs $1,397 a month, essentially level with the national figure, or roughly $16,764 across a full year. A household on the local median income would put about 22.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 8.9×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 66.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 8.9× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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 98831 in context

How 98831 sits inside Chelan County and Washington.

ZIP 98831 is tabulated inside Chelan County, Washington, one of 13 ZIP areas the Census publishes for that county and 605 across Washington. Population sits in the small-town band, typically one main street plus the addresses that feed into it. 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 98831 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 98831 reports a median household income of $73,223, close to the $74,768 county median, and 9% below the $80,861 typical WA ZIP. Owner-occupied homes are valued at a median of $652,300, 48% above the county figure and 55% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,397 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Washington charges 6.5% statewide, and local governments overlapping 98831 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

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 98831 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.
