Population shapes and quizzzzz

Today we got our quizzes back, and I did pretty well. Apparently, the classes before didn't have notes for this quiz and they got higher grades than us, which isn't that good. To get on an even happier note is that we have a test on Friday, about migration and population, which sounds like it might be hard, so hopefully I can do well on it. The last thing that we did was look at some states to see which type of shape they are and what kind of age of population they have. For example, Ann Arbor, Michigan has a lot of people between their 20's and their 30's, because Ann Arbor is a huge college town. Another example is F. Bragg, North Carolina, and in this state there is a lot more men in their 20's, because it is a big military place there. The last state we looked at is Florida. Florida, obviously has a higher population in older people, because it's warm and there isn't too many young kids running around, therefore this creates a hot spot in retirement.
