The US Population Center Is in This Tiny Missouri Town — And It’s a Quick Route 66 Detour

Set in Wright County in south-central Missouri, Hartville isn’t directly on Route 66, but it’s an easy detour if you’re traveling between Springfield and the Oklahoma border. The marker itself sits just outside town along a rural road, with a large red granite monument marking the spot. There’s no visitor center or formal site — just a red granite marker set along a rural road marking the point.

To find the center of the US, the Census Bureau uses data collected every 10 years, calculating what it calls the “center of population.” This point represents the place where the country would balance if every resident had equal weight on a flat surface. The method has been used for more than a century and offers a simple way to track how the population shifts over time.

That shift has been gradual but consistent. The country’s population center has been in Missouri since 1980, and before Hartville, it was located about 12 miles away near Plato, Missouri. Each decade, the point has inched generally south and west, reflecting population growth in states like Texas, Florida, and across the Southeast. The move to Hartville represents one of the smallest shifts on record, but it continues that long-term trend.

Hartville itself is still a small, working town. There’s little here built around tourism — most people stop briefly, then continue on. After a quick visit, most travelers continue on to Springfield, about an hour away, where Route 66 history, restaurants, and larger attractions pick back up.

It’s an easy place to pull over if you’re already driving through this part of Missouri — a quick stop to stretch your legs, take a look at the marker, and say you’ve stood at the center of the country’s population.
