Review and Population Pyramid

 Review
Today in class we had a delicious chocolate cake brought in by Owen. Although, he forgot to bring utensils, plates, and napkins so it was hard to cut and eat but I managed because it was so good. While we did all of this Mr Schick went over the powerpoint and explained things in more detail. One thing that was cleared up was the TFR and how it has to be 2.1. Since no woman can have 2.1 babies you find the average between the women which then equals 2.1.

Pyramids
We use population pyramid to analyze growth (or decline) of fertility, morality, and migration in the cities.
