Final Answer:
The ratio of residents expected to be over 65 years old is a demographic indicator used to assess the aging population within a specific area.
Step-by-step explanation:
Demographic indicators, such as the ratio of residents over 65, provide insights into the age distribution of a population. This ratio is calculated by dividing the number of residents aged 65 and above by the total population. It is a crucial factor for policymakers, urban planners, and healthcare professionals to anticipate and address the needs associated with an aging population.
Understanding this ratio helps in planning for healthcare services, social support, and infrastructure to accommodate the unique requirements of older residents. As this ratio increases, there may be a higher demand for elderly care facilities, healthcare resources, and age-friendly urban planning.
In summary, the ratio of residents expected to be over 65 years old is a valuable demographic metric that informs strategic planning for communities to ensure the well-being and quality of life for their aging population.
