Many people may assume that the city of Boise is located in Boise County, Idaho, but that is not the case. The city of Boise is actually situated in Ada County, while Boise County is home to the smaller town of Idaho City and the Boise National Forest. The Boise Basin in Boise County was an important area of growth in the mid-1800s as Idaho developed into a state, but for some reason the city of Boise itself was not placed in the county that shares its name.

Why it matters

This geographic distinction between Boise City and Boise County is an important one, as the two locations are quite different in character. Boise City is a modern, industrialized urban center, while Boise County is largely a mountainous, rural area. Knowing whether someone is from the city or the county can provide useful context about their background and experiences.

The details

The Boise County Sheriff's Office recently shared a social media post attempting to highlight the key differences between Boise City and Boise County. The post paints the county as more rugged and blue-collar, while characterizing the city as home to "mama's boy hipsters" and yoga enthusiasts. While this is a hasty generalization, there is some truth to the contrasting demographics and lifestyles between the two locations.
