Importance of population projection
Population projection is important since it can help people make important decisions about future. I will list some potential ways that people can use the result of population projection.
1. Estimate the basic need for human, such as demand for food, water, power, transportations.
2. Plan constructions such as housing, highways etc.
3. Estimate the labor forces in various places.
4. Estimate the potential consumptions in various regions.
5. Benefit sociological research, such as providing data about sex ratio or age ratio.
