Some point of interest that I’ve noticed just by glancing over (I agree that some more analysis would be nice):
Cities seem to have a slightly higher percentage of 14 and younger than most of the neighboring areas. I don’t have a quick theory as to why.
Some rural counties have a remarkably high percentage that I don’t have a specific reason for.
Areas near the border with Mexico seem to have a higher percentage of 14 and younger than the average. I guess that immigration has the most to do with it.
Utah has a much higher average than the neighboring area. I’ll give you three guesses why and the first two don’t count.
