Age structure refers the proportion of people in different age groupsrelative to the total population. Demographic dividend is the opposite of the phenomenon mentioned above. Population momentum is an unrelated concept in this case.

Ageing of the population refers to a shift in the age structure of a population, where there are relatively smaller proportions of the population in the younger age groups and larger proportions in the older age groups. This phenomenon occurs when the fertility rates decline and life expectancy increases.
Below are the key points explaining the answer:
1. Ageing of the population:
- Ageing of the population refers to the process where the proportion of older individuals in a population increases over time.
- It is characterized by a decline in the proportion of younger age groups (children and young adults) and an increase in the proportion of older age groups (elderly).
2. Smaller proportions in younger age groups:
- As the population ages, the fertility rates tend to decline, resulting in fewer children being born.
- This leads to a relatively smaller proportion of the population being found in the younger age groups.
3. Larger proportions in older age groups:
- At the same time, improvements in healthcare, nutrition, and living conditions have led to increased life expectancy.
- This means that people are living longer, resulting in a larger proportion of the population being found in the older age groups.
4. Impact on the age structure:
- The ageing of the population has significant implications for societies and economies.
- It can lead to increased healthcare and social welfare costs as the older population requires more medical and support services.
- It can also impact the labor force and economic productivity, as a smaller proportion of the population is in the working-age group.
In conclusion, the term "ageing of the population" refers to a demographic phenomenon where there is a shift in the age structure, with smaller proportions in the younger age groups and larger proportions in the older age groups. This trend has important implications for societies and economies, requiring them to adapt to the changing needs and demands of an ageing population.
