Below is an approximate analysis of that map’s shading and the 100-mile radius around 39°06′09.2″N 94°35′01.8″W (near Arrowhead Stadium):
-
Identify the “Chiefs” Counties
On the Vivid Seats map, all counties shadedrgb(227, 24, 55)
represent the most popular Kansas City Chiefs counties. From that map, the Chiefs territory covers a large portion of western and central Missouri (though not necessarily all of it), a large swath of eastern and central Kansas, and potentially overlaps parts of Iowa and Nebraska. -
Draw a 100-Mile Radius Circle
The center coordinate, 39°06′09.2″N 94°35′01.8″W, is located in Kansas City, MO—very close to Arrowhead Stadium. A 100-mile radius from that point would encompass the Kansas City metropolitan area and extend roughly:- Eastward past Columbia’s outskirts (but not all the way to St. Louis).
- Westward beyond Topeka, KS.
- Northward approaching (or slightly past) the Iowa border in some directions.
- Southward toward the edge of the Ozarks region.
-
Counties Within and Outside
Because this is a broad estimate using the color-coded map and not official data, we can approximate how many counties within that circle are primarily Chiefs-fan counties vs. how many outside that circle are still shaded Chiefs colors. -
Approximate Results
From visually inspecting the shape of those “Chiefs” shaded areas, a significant portion of them lies beyond 100 miles from central Kansas City (portions of western Kansas, Nebraska, Iowa, etc.). Thus, it appears that a large fraction of the “Chiefs” counties—well over half—lies outside of that 100-mile radius ring.A rough approximate is that perhaps 35–45% of the “Chiefs” counties lie within the circle and 55–65% fall outside. Based on an estimation of how the coloring extends into multiple states, around 60% is a reasonable approximation for the share of those
rgb(227, 24, 55)
counties outside of a 100-mile radius.
Hence, the best approximate figure is about 60% outside the 100-mile radius. Any more precise calculation would require overlaying GIS data with county boundaries, but visually from that map, roughly three-fifths appear to lie outside the immediate 100-mile ring from Arrowhead.
