The term "aging population" refers to a group or society where an increasing proportion of people are aged 65 and over. This phenomenon is often attributed to improvements in healthcare, nutrition, and overall quality of life which have led to longer lifespans and fewer deaths from infectious diseases. As the number of older individuals grows relative to younger generations, it can present various challenges for societies including increased demand for health care services, pensions, and long-term care facilities. Additionally, an aging population may also impact economic growth, as there are fewer people in the workforce to support those who have retired.
