Largest State Capitals | Trails Unblazed

State Capitals Ranked by Population

While some state capitals are bustling metropolises that serve as the crown jewels of their regions, others are quiet, historic towns where the pace of life remains remarkably local. From the sprawling desert landscape of Phoenix, which leads the pack with over 1.6 million residents, to the charming, small-town atmosphere of Montpelier, home to fewer than 8,000 people, the population of these political hubs varies as much as the states themselves. This list ranks all 50 U.S. state capitals by their latest population data, offering a unique look at how these centers of government measure up—from the massive urban centers of the Sun Belt to the hidden gems of New England.
