What are the stages of the demographic transition model?

The stages of the demographic transition model are as follows:

1. Stage 1: High stationary
- High birth rates and high death rates
- Population growth is slow and stable

2. Stage 2: Early expanding
- High birth rates and declining death rates
- Rapid population growth due to improved healthcare and sanitation

3. Stage 3: Late expanding
- Declining birth rates and low death rates
- Population growth slows down as contraception becomes more accessible and urbanization increases

4. Stage 4: Low stationary
- Low birth rates and low death rates
- Population growth is very slow or stagnant
- Population may even decline in some cases

Some models also include a Stage 5, which represents a potential future stage characterized by very low birth rates, an aging population, and population decline.
