Population Growth

Family welfare is linked with health and population awareness. Exam tip: connect it with population stabilisation.

Better health services can reduce deaths. Exam tip: link health improvement with lower death rate.

Growth may be rapid when births are high and deaths are low. Exam tip: remember birth death gap.

Census provides official population for different years. Exam tip: remember census as official source.

Population may remain stable when additions and reductions are equal. Exam tip: remember population balance.

When both the birth rate and death rate are low, the difference between births and deaths is usually small. Therefore, population growth may be slow or nearly stable. Very rapid growth occurs when the birth rate is much higher than the death rate. Exam tip: compare the difference between birth rate and death rate to judge natural growth.

Population growth means the change in the population of an area between one point in time and another. Therefore, it is always measured for a specific period, such as one year or ten years. Option C gives population at a single point, but growth requires comparison between at least two points in time. Exam tip: use the phrase “change during a specific time period” in your answer.

Percentage growth shows change based on old population. Exam tip: remember base population.

When people enter an area from elsewhere for work, education, or other reasons, it is called in-migration. It may increase the population of that area. Out-migration means people leaving an area. Exam tip: link ‘coming in’ with in-migration and ‘going out’ with out-migration.

When people leave an area for another place because of a push factor such as lack of jobs, it is called out-migration. Therefore, out-migration is correct. In-migration means people moving into an area, so it does not fit here. Exam tip: link “leaving an area” with out-migration.

High births and low deaths increase natural growth. Exam tip: remember high birth low death.

Population can decrease when deaths and out-migration (people leaving an area) are high. Deaths reduce the number of people, and out-migration removes people from that area. In contrast, births and in-migration increase population. Exam tip: births and in-migration are added to population, while deaths and out-migration are subtracted.

More population in cities increases crowding and housing demand. Exam tip: remember urban pressure.

Growth information helps plan schools hospitals roads and jobs. Exam tip: link growth data with planning.

Education and health awareness help family welfare. Exam tip: remember welfare approach.

Population size and growth are different concepts. Exam tip: separate number at a time and change over time.

For a fair comparison of population growth, the time period must be the same, such as comparing the change in population of two areas over 10 years. If the periods differ, the area measured for longer may appear to have greater growth simply because more time has passed. Initial population or area may be useful data, but neither replaces an equal time period. Exam tip: check the number of years first when comparing growth or growth rates.

Difference between new and old population is absolute growth. Exam tip: remember actual difference.

High births and low leaving can cause growth. Exam tip: identify additions and reductions.

High deaths reduce the number of people in an area, and out-migration also removes people from that area. Therefore, when both occur, the population may decrease. Increased in-migration or a doubled birth rate does not necessarily follow from these conditions. Exam tip: births and in-migration add to population, while deaths and out-migration reduce it.
