How can we model population change? (p. 94 - 95)

How can we model population change?
Goals:

At the end of these two classes you:
- understand how to interpet different population charts
- understand how changes to birth and death rates can be modelled
- understand how differences in the share of different age groups tot the total population can lead to demographic pressure
