the demographic transition

So today in human geo Mr. Schick basically just talked about ho exams are really soon and how they're gonna work and stuff like that. Then he gave us this article on the demographic transition and told us to read it and highlight/ underline information we think seems important. As I was reading and highlighting important stuff, I came across a lot of the same stuff we did in our last unit with population and settlement stuff. Like it pretty much just talked about how the CDR, the CBR, and the NIR, affect countries and their growth. Im not really sure if that's exactly right, but that's what I got from it.
