Ageing population is the result of _____.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Decline in birth rate and increased life expectancy
An ageing population occurs when:
-
Birth rates decline, leading to fewer young people being born.
-
Life expectancy increases, allowing more people to live longer.
This combination results in a larger proportion of elderly people in the total population, a trend commonly seen in developed countries like Japan and Germany.
