Birth rate in a population is calculated as: (1) Increase in numbers with respect to members of the population

The birth rate in a population is a measure of the rate at which new individuals are added to the population through reproduction. It indicates the reproductive capacity and potential growth of the population. To calculate the birth rate, we consider the increase in numbers with respect to the total members of the population.

For example, let's consider a population of rose. There were 100 rose plants in a garden last year. 20 new rose plants are added through reproduction in current year. The population increased to 120 rose. We can calculate the birth rate as follows:

Birth Rate =20 /100 = 0.2
