Idaho cities and towns

This directory lists every place the US Census Bureau tabulates in Idaho, ranked from the largest to the smallest by population. Incorporated cities, towns and villages appear alongside census-designated places (CDPs) — unincorporated communities that have no local government of their own but are counted separately because they have a recognised name and settled population. The suffix in each name ("city", "town", "village", "CDP") is the Census legal/statistical description, which is why you will see entries such as "Boise City city".

The largest place in Idaho is Boise City city with 235,701 residents, and the 236 places on this page hold 1,381,127 people between them. Median household income across the listed places runs from $25,833 to $159,439, and median home values range from $75,800 to $981,300 — a spread that shows how much local housing markets diverge inside a single state.

Every figure comes from the American Community Survey 2019-2023 ACS 5-year five-year estimates, which average survey responses over sixty months. That averaging is what makes small towns measurable at all, but it also means the numbers describe the period as a whole rather than today. Blank cells are estimates the Census suppressed because the local sample was too small to publish reliably. Select any place to open its full profile with affordability ratios, poverty and homeownership rates, and links to nearby communities of similar size.

Population in Idaho is tightly clustered: the ten largest places carry 61% of the 1,381,127 residents counted across all 236. Boise City city sets the pace and everything outside the top ten is genuinely small, so statewide averages describe the cluster rather than the state. These are mostly very small areas — the median place counts 780 residents. Rankings at the bottom of this list are within each other's margin of error, so treat close positions as ties.

On housing, Idaho tracks the national pattern closely: $238,900 median home value against $63,125 median income, a ratio of 3.8 versus 3.9 nationally. Rent stays modest against earnings — $940 a month, roughly 18% 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: $43,125 to $87,658 across the tenth-to-ninetieth percentile band, a 2.03× spread. Hidden Springs CDP tops the list at $159,439 and Tensed city anchors the bottom at $25,833, but those two are not where most of this list sits.

About one row in 10 is incomplete — 23 of 236 places 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.

How many places does Idaho have? 236 appear in the current federal tabulation, counting incorporated cities, towns and villages together with census-designated places — unincorporated communities with no local government of their own. 58% of them have fewer than a thousand residents, so the list is far longer than the number of towns you would recognise by name.

Which Idaho row should I compare mine against? Not the state median — it is pulled by the Idaho core. Compare against places in the same population band, which for most of this list means the entries below the top ten.

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 places this small.
