Population refers to the number of human beings living in a particular region at a particular time.

The size of the population is ascertained through national headcount, which is referred to as a national census. It is an international requirement that each country must hold a national census at least every ten years.

Population issues are major concerns to business people because people are consumers of goods and services as well as providers of factors of production.
