What this Idaho ranking shows
According to the U.S. Census Bureau's American Community Survey (ACS) 5-year estimates, the CDC PLACES population-level health analysis, and the CMS Hospital Compare quality data, Areazine ranks U.S. cities across more than 19,000 incorporated places, census-designated places, and consolidated city-county governments. State-level city rankings combine these federal datasets to produce intra-state comparisons across demographics, economics, health outcomes, and hospital quality.
Meridian leads 21 Idaho cities at 130,138, while Burley sits at the bottom with 11,958 - a total spread of 118,180 on population. The top 5 occupy 61% of that range, indicating a wide separation between leaders and the rest of the field.
The median Idaho city in this list sits at 32,855, 97,283 behind Meridian. See our methodology for ranking construction, data vintage, refresh cadence, and the federal upstream tables we join, and triangulate via the 8 other Idaho rankings below, cities that lead on multiple lenses are the most robust signals.

Reading this Idaho ranking responsibly
Single-metric rankings are useful precisely because they are honest about what they measure. A "highest income" ranking does not tell you that the top-ranked city is the best place to live in Idaho; it tells you that, among cities of population ten thousand and above in Idaho that have a published median household income field in the most recent American Community Survey five-year estimates, this city has the highest such value. That precise definition matters, because composite "best places" lists from real-estate marketing sites and lifestyle magazines often combine income with subjective weights on schools, walkability, and amenities, producing a score whose components are not disclosed and whose ordering is not reproducible. Areazine's editorial commitment is to keep the underlying field, source, and vintage visible so the reader can audit any rank in this list against the canonical federal record.
Cross-checking against other rankings is a useful sanity test. A city that appears in the top ten on three or more different rankings, for example, highest income, most educated, and lowest poverty, is showing a robust signal across multiple independent dimensions. A city that appears in the top ten on only one ranking and middling on the others is showing a narrower signal, often driven by a single statistical artifact (a small population pulling the per-capita measure, a recent acquisition spike inflating median home value, an outlier survey year). The other nine Idaho rankings linked above provide that cross-check at zero extra effort.
