Reading this Idaho list

What the Idaho numbers actually show.

Idaho is unusually decentralised. No single centre dominates — the ten largest ZIP codes together hold just 29% of the 1,893,322 residents here, and 48 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. The median row holds just 1,358 residents. At that scale margins of error widen sharply, and a single large household or seasonal population can shift a median.

On housing, Idaho tracks the national pattern closely: $296,900 median home value against $68,377 median income, a ratio of 4.3 versus 3.9 nationally. Rent stays modest against earnings — $940 a month, roughly 16% of median household income over a year. The statewide midpoint hides real variation, though — that is what the spread below is for.

Middle-of-the-road dispersion: $48,438 to $91,034 across the tenth-to-ninetieth percentile band, a 1.88× spread. 83848 tops the list at $146,058 and 83209 anchors the bottom at $18,935, but those two are not where most of this list sits.

About one row in 9 is incomplete — 30 of 280 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 Idaho.

How many ZIP codes does Idaho have? 280 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 Idaho, and PO-box-only ZIPs have no area at all.

Which Idaho 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.
