What does the term rate of natural population increase refer to?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. The gap between birth rate and death rate

The correct definition is: The gap between birth rate and death rate.

The Rate of Natural Population Increase (RNI) is a fundamental demographic measure calculated by subtracting the Crude Death Rate (CDR) from the Crude Birth Rate (CBR).

RNI = Crude Birth Rate - Crude Death Rate

It indicates a population's growth (or decrease, if negative) based solely on natural factors (births and deaths), excluding the effects of migration. This pure measure is crucial for demographers to place a country within the Demographic Transition Model.

Explaining Other Options:

  • The total number of children born per family: This refers to the Total Fertility Rate (TFR), which is the average number of children a woman would have in her lifetime.

  • The rise in population due to migration: This is known as Net Migration (Immigrants minus Emigrants) and is a separate component that, when combined with the RNI, gives the Total Population Growth Rate.

  • The percentage of population living in urban areas: This is a measure of Urbanization and has no direct relation to the rate of natural increase.
