Index, WA population, income and ZIP codes

Index town is a very small community in Washington, with 164 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #571 of 639 ranked by population — larger than 10% of them. The median age here is 48.5 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 Index town earn a median of not published a year. 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 11.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Index town is valued at $481,800, 58.8% above the national figure and 3% above the $468,400 peer median, while median gross rent runs not published a month. 90.3% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 164 residents, a handful of survey responses moves every median on this page. Compare Index town against its county rather than against national figures.

The Census withheld household income, gross rent for Index town 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.
