The correct answer is Births, deaths, and migration.
Population change:
- Population change, defined generally, is the difference in the size of a population between the end and the beginning of a given time period (usually one year).
- The main components of population change are births, deaths, and migration. Hence statement 2 is correct.
- “Natural increase” is defined as the difference between live births and deaths.
- “Net migration” is defined as the difference between the number of people moving into an area and the number of people moving out.
- The population change is calculated by the formula -- [Population change = (Births + Immigration) – (Deaths + Emigration)]

Factors of Population Change:
Births:
- The number of births in a population directly impacts its growth rate. High birth rates contribute to population increase, while low birth rates can lead to a decrease in population size.
Deaths:
- The number of deaths in a population also plays a significant role in determining overall population change. High death rates can result in a decline in population, while low death rates can lead to population growth.
Migration:
- Migration refers to the movement of individuals from one place to another. It can have a substantial impact on population change, as individuals moving into a region can increase its population size, while those leaving can decrease it.
Overall, births, deaths, and migration are the three main factors that influence population change. By understanding how these factors interact and affect population dynamics, researchers and policymakers can better plan for future demographic trends.
