The Geographic Center of the United States Is in a Kansas Town You've Never Heard Of

Finding the Middle of a Nation

The U.S. Geological Survey first calculated the geographic center of the contiguous 48 states in 1918 using a method that was elegant in its simplicity and more than a little charming in retrospect: they cut out a cardboard map of the continental United States and balanced it on a pin, much like finding the center of mass of an irregular shape in a high school physics class. The point at which the map balanced was recorded as the geographic center, and calculations placed it in Smith County, Kansas, approximately 2.6 miles northwest of the town of Lebanon.

The location was formally marked in 1940 when a local businessman named Johnny Grib installed a stone monument on the property. The site today features the original limestone marker, a small flag, and a chapel that was added in the 1950s. The tiny town of Lebanon, which has a population of only a few hundred people, has leaned into its geographic distinction with a marker near the town center and occasional mention in trivia competitions.

What "Geographic Center" Actually Means

The term geographic center is more ambiguous than it sounds. There are multiple ways to define the center of an irregular shape, and different methods produce different answers. The USGS definition is essentially the center of gravity of the flat surface area — the point at which a flat, weightless cutout of the territory would balance. This differs from the geometric centroid calculated using latitude and longitude coordinates, which places the center slightly differently due to the Earth's curvature.

It also matters enormously which territory you include. The center of the contiguous 48 states, excluding Alaska and Hawaii, falls in Kansas as described. When Alaska is included — which is enormous and extends far to the north and west — the geographic center shifts dramatically northward into South Dakota or even further. If Hawaii is added, the calculation moves again. The USGS maintains different official centers depending on which definition of "United States" is used.

Lebanon, Kansas, and the Nature of Geographic Centers

What makes the Lebanon, Kansas location interesting is not the monument itself but what it reveals about the geometry of the country. The United States is not symmetric in any intuitive sense — the East Coast has dense population and many states packed into a small area, while the West has vast open expanses. Yet when you balance the total land area, the midpoint ends up in the High Plains of Kansas, which feels geographically apt: a region of wheat fields, sky, and wind that sits at the confluence of nothing in particular except the arithmetic of a continent's shape.

Geographic centers of political entities have attracted human fascination and sometimes human settlement throughout history. The geographic center of England, the center of Europe, and the centers of various US states are all marked in similar ways — small monuments in unremarkable locations that have been elevated to significance purely by the mathematics of their position. They invite a peculiar form of pilgrimage, undertaken not for religious or scenic reasons but out of a desire to stand at a calculated point and feel the geometry of a large thing resolved to a single location.

The Town That Exists Because of a Calculation

Lebanon, Kansas, has a population that has declined steadily for decades as the agricultural economy of the High Plains has contracted. The geographic center designation is now one of the town's primary identities — a distinction earned not by anything Lebanon's residents did but by an act of mathematical fortune. The monument draws a modest but steady stream of visitors who cross miles of Kansas plains to stand at a point that was determined by balancing a piece of cardboard more than a century ago, which is, when you think about it, a perfectly good reason to drive somewhere.
