Some cities like Portland, Oregon, are known for being hipster havens, but increasingly, more under-the-radar places are becoming hotspots for millennials.

Smaller cities like Boise, Idaho and Spokane, Washington, are not only filled with vegan stores, microbreweries, and thrift stores, but they’re also more affordable to live in than many bigger cities.

MoveHub created a US Hipster Index that ranked cities based on a variety of factors that make them appealing to young people. The index takes into account the density of tattoo parlors, vegan stores, microbreweries, and thrift stores, as well as any increases in rent.
