2. Can easily fall back into rapid growth

3. Declining fertility and mortality rates

4. Beginnings of better education, medical, and working condition

*Newly Industrialized

Stable Growth Negative Growth

1. As countries develop, they go from one stage to the next, or even back a step.

2. Not all countries want a negative population, so they actively seek ways to maintain their healthy populations while not overpopulating.
