An aging population is a population in which the number of old persons is increasing. This means that the proportion of the population made up of older people is increasing relative to the proportion of younger people. The definition of "old" varies depending on the context and the country, but it generally refers to people over a certain age, such as 65 or 70 years old.
An aging population is characterized by a shift in the age distribution of a population towards older ages. This can occur due to various factors such as declining birth rates, improved healthcare, and increased life expectancy. As a result, the proportion of older people in the population increases, while the proportion of younger people decreases.
An aging population can have significant social and economic implications, including increased demand for healthcare and social services, changes in workforce participation and retirement patterns, and shifts in consumer spending patterns. It can also have implications for government policies related to social security, healthcare, and pension systems.
Therefore, an aging population is a population in which the number of old persons is increasing, leading to a shift in the age distribution of the population towards older ages.
