Northwest Arkansas and Central Arkansas have the biggiest population percentiles. It seems the outer right hand portion of Arkansas also has a high population percentile. As you move down the map, the population percentiles get lower and lower.

Northwest Arkansas, FortSmith Area, and Central Arkansas have the biggest cluster of subways. The other subways are spread out and mainly on big highways. Overall, a lot of subways are found throughout Arkansas.

Areas in Arkansas with the highest population percentiles also have the highest number of subways in that area. Areas that don’t have as big of a population percentile, have very little subways in their area. The majority of subways in Arkansas are found in the northern region.
