I found this interesting. This is a good way to see how our country has evolved in population over the last 150 years. I've heard so many stories about where some of the older generations settled, but I kept getting confused by the different peoples that seemed to live in the same places. I'm leaving the pictures in thumbnail size for obvious reasons.
I had to split the list, and I know it can be a hassle to go through all of charts, but it is very interesting to see how this country has changed.
