Reading this Washington list

What the Washington numbers actually show.

Washington is unusually decentralised. No single centre dominates — the ten largest ZIP codes together hold just 8% of the 7,740,873 residents here, and 233 separate entries clear 10,000 people. State-level averages are more representative here than in most states, because there is no outsized core pulling them. Half of these ZIP codes hold more than 4,632 residents, which is a small-town scale: big enough for published estimates, small enough that one employer or one subdivision moves the numbers.

Washington sits on the expensive side of the national picture without being an outlier: $421,200 median home value on $80,861 of income is 5.2 years of gross earnings against 3.9 nationally. Median gross rent runs $1,305 including utilities, or about 19% of median household income annually.

The internal range is wide but not exceptional: $127,081 at the ninetieth percentile against $51,094 at the tenth, a 2.49× gap. At the edges, 98075 tops the list at $250,001 and 99034 anchors the bottom at $11,288.

About one row in 13 is incomplete — 49 of 605 ZIP codes have a suppressed estimate, almost all of them at the small end. Five-year estimates average responses over sixty months, so what is published is a stable baseline rather than a reading of this month's market.

Questions people ask

Specific to Washington.

How many ZIP codes does Washington have? 605 appear in the current federal tabulation. ZIP code tabulation areas are the Census approximation of postal ZIP codes, so the count differs slightly from the number of ZIPs the Postal Service delivers to in Washington, and PO-box-only ZIPs have no area at all.

Which Washington row should I compare mine against? Pick ZIP codes within roughly the same population band. In a state this spread out, size drives the housing and income figures more than region does.

How current is this? Every figure comes from the American Community Survey 2019-2023 ACS 5-year release published by the US Census Bureau, ACS 2019-2023 5-year estimates. It reflects the full survey window rather than a single date, and it is the most recent vintage available for ZIP codes this small.
