1. Birth rate (natality)- It is the ratio of live births in an area to the population of an area. It is expressed as the number of individuals added to the population.

2. Death rate(mortality)- It refers to the live deaths in an area to the population of an area. It is expressed as the number of individuals removes from the population. 

3. Sex ratio- It is the ratio of the number of male or female individuals per 1000 individuals.
