Population

Population refers to all the organisms of the same group or species, which live in a particular geographical area and have the capability of interbreeding. In the context of human population, it refers to the total number of people living in a particular area.

Factors Affecting Population

1. Birth Rate: The number of births per 1,000 people in a year.
2. Death Rate: The number of deaths per 1,000 people in a year.
3. Migration: The movement of people into and out of a specific area.
4. Life Expectancy: The average age to which a person is expected to live.

Population Growth

Population growth is influenced by the birth rate, death rate, and migration. If the birth rate is higher than the death rate, the population will grow. If the death rate is higher than the birth rate, the population will decline. Migration can also contribute to population growth or decline.

Impact of Population

Population size influences the demand for resources, environmental impact, and social dynamics. It can lead to issues such as overpopulation, strain on resources, and environmental degradation.
