Most countries of the world are either over-populated, under-populated or having optimum population

Over-Population: This is a situation whereby the number of people living in a country is far more than the available resources of the country.

Under-Population: This is a type of population in which the number of people living in a country is far below the available resources of that country.

Optimum Population: This is a situation whereby the number of people living in a country is neither too small nor too great compared to the available resources of that country.
