Fort Lewis, WA population, income and ZIP codes

Fort Lewis CDP is a mid-size town in Washington, with 13,983 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #96 of 639 ranked by population — larger than 85% of them. The median age here is 23 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Fort Lewis CDP earn a median of $54,902 a year, 30.1% below the national figure of $78,538 and 39% below the $90,592 median for the 393 Washington cities we cover. 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 16.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Fort Lewis CDP is valued at not published, while median gross rent runs $2,240 a month, 59.3% above the national figure, or roughly $26,880 across a full year. A household on the local median income would put about 49% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is severely stretched — a median-income renter clears the cost-burden line by a wide margin before utilities beyond the gross-rent definition. 1.8% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 23 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

The Census withheld home value for Fort Lewis CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
