What demographic group is identified as being 65 years or older?

The demographic group identified as being 65 years or older is referred to as "Aged." This classification is commonly used in demographic and social research to denote a segment of the population that has reached a certain milestone in terms of aging. The term "Aged" aligns with various health, economic, and social policies that are specifically designed to address the needs and challenges faced by this group.

"Senior Citizens," while often used interchangeably with "Aged," is a more informal term and does not have the same scholarly or policy-oriented context. Similarly, "Elderly" is a term that describes older individuals but can carry connotations that are not always favorable in discussions about aging. "Retired Individuals" focuses specifically on those who are no longer in the workforce, which doesn't necessarily encompass all individuals aged 65 and older, as some may continue working. Therefore, "Aged" is the most precise descriptor for the demographic group in question.
