Question

Answer

other than natural change in Birth rate and Death rate, what changes the no. of Popuation of an area is migration.

Answer

Natural Change and Net Migration are the two factors that affect population change for a particular area.

Natural Change: This factor refers to the difference between the number of births and the number of deaths in a population.

Net Migration: Net migration is the difference between the number of people immigrating to an area and the number of people emigrating from that area. Positive net migration occurs when more people are moving into an area than leaving it, leading to population growth. Negative net migration occurs when more people are leaving an area than arriving, resulting in population decline.

Answer

Factors Affecting Population Change
Population change in a particular area is influenced by various factors, with two key factors being Natural Change and Migration.
Natural Change
- Natural change refers to the difference between the number of births and deaths in a population.
- When the number of births exceeds the number of deaths, the population increases, leading to growth.
- Conversely, if the number of deaths surpasses the number of births, the population declines, resulting in negative growth.
- Natural change is influenced by factors such as fertility rates, mortality rates, and life expectancy.
Migration
- Migration plays a crucial role in population change by involving the movement of people into or out of a particular area.
- Immigration, or the influx of individuals into a region, contributes to population growth.
- Emigration, which involves people leaving a region, can lead to population decline.
- Migration patterns are influenced by various factors such as economic opportunities, political conditions, and social factors.
In conclusion, while Natural Change focuses on the balance between births and deaths within a population, Migration deals with the movement of individuals in and out of a specific area. Both factors are essential in understanding and predicting population change in a given region.
