Question

define population growth.what are the various methods of calculating population growth​

Answer 1

Answer:

We can write a simple equation to show population growth as: Change in Population Size = (Births + Immigration) - (Deaths + Emigration) Expressing Population Changes as a Percentage. Suppose we had a population of 100,000 individuals. Suppose in one year there were 1000 births, and 500 deaths.

Answer 2

Answer:

Population growth is the increase in the number of individuals in a population. ... Many nations with rapid population growth have low standards of living, whereas many nations with low rates of population growth have high standards of living.

Population growth rate is the percentage change in the size of the population in a year. It is calculated by dividing the number of people added to a population in a year (Natural Increase + Net In-Migration) by the population size at the start of the year.
