Fairfield town, WA in context

How this area compares with national benchmarks.

Fairfield town is a very small community in Washington, with 607 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #453 of 639 ranked by population — larger than 29% of them. The median age here is 39.8 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Fairfield town earn a median of $75,000 a year, 4.5% below the national figure of $78,538 and 17% below the $90,592 median for the 393 Washington cities we cover. 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 12.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Fairfield town is valued at $233,500, 23% below the national figure and 50% below the $468,400 peer median, while median gross rent runs $1,160 a month, 17.5% below the national figure, or roughly $13,920 across a full year. A household on the local median income would put about 18.6% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 74.7% 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.
