Which one of the following is a correct statement?

The correct answer is Option (3) → Growth rate of population is the change of population expressed in percentage.

Population change has three components: births, deaths and migration.

Option (1) Natural growth of population depends on births, deaths and migration. — Incorrect. Natural growth is only births minus deaths. Migration is added when we work out the actual growth.

Option (2) Crude death rates cannot be more than crude birth rates. — Incorrect. They can. When the birth rate falls below the death rate, the population shows negative growth.

Option (3) Growth rate of population is the change of population expressed in percentage. — Correct. The growth of population is the change in numbers; the growth rate shows the same change as a percentage.

Option (4) Migration is not a component of population change. — Incorrect. Migration is one of the three components, along with births and deaths.
