ZIP Code Tabulation Areas (ZCTAs) are specialized geographic representations crafted by the Census Bureau to roughly match U.S. Postal Service ZIP codes. Unlike standard postal areas, ZCTAs are crafted for statistical purposes, allowing detailed demographic data collection aligned to ZIP code-like areas.
In Cascade County, MT, the ZCTAs span several areas, with the lowest ZIP code starting at 59401 in the central hub of Great Falls, and extending to higher ZIPs that cover less populated rural locales. This range helps to identify population density differences within the county.
The ZIP codes in Cascade County serve multiple cities and towns, with Great Falls being the principal city. Smaller towns, alongside rural communities, are also represented in these ZCTAs, each contributing unique demographic data to the county's overall profile.
From urban Great Falls to rural ZCTAs, Cascade County’s demographics reveal varied population levels, household income distributions, and diverse race and gender profiles. The ZCTA with the largest population is centered in Great Falls, providing insights into employment, housing, and education levels, while smaller ZCTAs portray distinct rural trends.
