Answer 1

Instructions:

• Understand the purpose of scaling down.
• Mention how birth rate, death rate, and migration affect population

Solution:

Migration, birth and death rate are the factors affecting the population of a country.

Birth rate:
Birth rate is the number of live births per 1000 persons in a year.

Death rate:
Death rate refers to the number of deaths per 1000 persons in a year. These two are the major components that affect the natural growth of any country’s population.

Migration:
Migration is the movement of people across regions and territories.

• When the birth rate increases and the death rate decreases, the population increases
• When the birth rate decreases and the death rate increases, the population decreases
• When the birth rate and death rate are equal, there is no change in the population
• Migration-Population increases in one region but decreases in another region.
