Sub-Topic 1: Meaning of Population and Determinants of Population Size and Growth

Meaning of Population

This is the total number of people (including children, the disabled, beggars and other persons) living within a geographical area or country at a particular time. The question of population gave rise to the need to conduct population census.

Determinants of Population Size and Growth

The following are the major factors determining the size and growth of population

1. Birth Rate
2. Death Rate
3. Migration
4. Religion
5. Modern Medicine

Birth Rate

This refers to the number of children born within a year out of every 1000 people in the country. Generally, birth rate is higher in West African countries than in the Western countries. Can you provide the reason for this?

Determinants of Birth Rate

1. Age and sex distribution of the population: – Females are more fertile than male, if the population of female in a particular country is more than the population of male, it increases the birth rate.
2. Family planning: – The practice of family planning in a country reduces the birth rate.
3. The quality of medical services available: – Improved medical services increase the birth rate.
4. The time of marriage (early marriage or late marriage):– Early marriage increases the birth rate while late marriage reduces the birth rate.
