The table below shows the total population of Mexico for the given years.

1. What was the average rate of change for the population from $1900\ \text{to}\ 1950$?

The average rate of change is the slope between two points.
Find the slope between $(1900,13.6)$ and $(1950,26.3)$.
Pay attention to the units.

2. What was the average rate of change from $1960\ \text{to}\ 2010$?

3. When was the population growth rate higher?
