Consider the following statements. Reduction in mortality always leads...
- Reduction in mortality normally leads to a rising population. A drop in fertility, on the other hand, slows down population growth, ultimately resulting in absolute declines. The total fertility rate (TFR) — the number of babies an average woman bears over her lifetime.
- A TFR of 2.1 is considered as “replacement-level fertility”. Simply understood, a woman having two children basically replaces herself and her partner with two new lives. Since all infants may not survive to realise their reproductive potential, the replacement TFR is taken at slightly above two. It ensures that each generation replaces itself.
- Populations can keep growing even with TFRs falling. De-growth requires TFRs to remain below replacement levels for extended periods. The effects of that — fewer children today becoming parents tomorrow and procreating just as much or less — may reflect only after a couple of generations.

Consider the following statements. Reduction in mortality always leads...
Reduction in mortality always leads to a rising population:
- This statement is incorrect. While a reduction in mortality rates can contribute to an increase in population, it is not the sole factor determining population growth. Other factors such as fertility rates and migration also play a significant role. Therefore, it is possible for mortality rates to decrease while the population remains stable or even declines due to other factors.
The total fertility rate (TFR) is the number of babies an average woman bears over her lifetime:
- This statement is correct. The total fertility rate (TFR) is a measure used to estimate the average number of children that would be born to a woman over her lifetime if she were to experience the current age-specific fertility rates throughout her reproductive years. It is often used as an indicator of a country's population growth potential.
Populations can keep growing even with total fertility rates (TFRs) falling:
- This statement is correct. While the total fertility rate (TFR) is an important factor in determining population growth, it is not the only factor. Populations can continue to grow even if TFRs are falling due to factors such as increased life expectancy, reduced mortality rates, and migration. These factors can offset the decline in fertility rates and contribute to population growth.
In conclusion, statement 2 and 3 are correct. Reduction in mortality rates does not always lead to a rising population, as other factors such as fertility rates and migration also influence population growth. The total fertility rate (TFR) is indeed a measure of the number of babies an average woman bears over her lifetime. Additionally, populations can continue to grow even if TFRs are falling due to other factors such as increased life expectancy, reduced mortality rates, and migration.
