Growth Component Method
Growth Component Method
A population projection method involving separate projections for birth rate, death rate, and migration by age-sex groups.
Mathematical Method Assumption
Mathematical Method Assumption
Mathematical population projection assumes demographic projection of the future is based on the growth rate of the past and that the prevailing situation will remain in the future too.

Study Notes
- Methods of Population Projection include the Arithmetical Increase Method, Geometrical Increase Method, Incremental Increase Method, and Graphical Method.
Limitations of Mathematical Method
- It is neither adequate nor complete for providing age group information in population projection.
- The method assumes that past growth rates will continue, which may not reflect future or past population trends accurately.
- It assumes birth rate, death rate, and migration as constants, failing to project changes in these rates.
- Socio-economic changes that significantly affect population growth are ignored, which can lead to inaccurate projections.
Growth Component Method
- This method is considered more practical than the mathematical method for population projection because, also known as the cohort component method, it makes separate projections for birth-rate, death rate, and migration by age-sex groups.
- Projections for birth rates by age-sex groups consider factors such as fertility rate in females, marriage and re-marriage rates, sterilization rate, socioeconomic factors, education, divorce, and net reproduction rate.
