Question
What are the three components of population change?
✓
Answer
The three components of population change are:
Crude Birth Rate (CBR): It is expressed as number of live births in a year per thousand of population in a particular region.
Crude Death Rate (CDR): It is the number of deaths in a place per thousand of population in a particular region. CBR and CDR are natural factors of population growth. They result in natural population growth, which is equal to the difference between CBR and CDR.
Migration: It is the induced factor in population growth. It is the number of people moving in and out of a place due to various social, economic and political reasons. It is taken into account while calculating actual growth of population.
