What does an inverted age pyramid indicate about a population?
The population has a high proportion of young individuals.
The population has a high proportion of individuals in their reproductive age.
The population has a balanced distribution of individuals across age groups.
The population has a high proportion of elderly individuals.
Correct option (d)
An inverted age pyramid, sometimes referred to as a "reverse" age pyramid or a "top-heavy" pyramid, is a population pyramid where the proportion of elderly people to young people is greater. This demonstrates that a significant section of the population is elderly, whereas a smaller portion is youthful.
Low birth rates and increased life expectancy frequently result in an inverted age pyramid, which causes the population's proportion of young people to decline and its proportion of elderly people to rise. The labour, healthcare, and social security systems, among other things, may be significantly impacted by this demographic change.
Option d is the correct answer.
