What term is used to describe individuals aged 65 or older who experience physical limitations?

The term that is most accurately used to describe individuals aged 65 or older who experience physical limitations is "Elderly population." This term encompasses a broader range of individuals within that age group who may face various health challenges, including physical limitations. It reflects considerations of age-related changes, chronic conditions, and the cumulative effects of aging on physical capabilities.

Using "Senior citizens" or "Active aged" could imply a more general and often more positive view of aging, typically associated with the notion of seniors engaged in community or active living, which may not focus specifically on the experience of physical limitations. "Well elderly" specifically refers to those seniors who maintain good health and do not have significant limitations or chronic health issues, which contrasts with the context of the question.

Therefore, "Elderly population" best captures the concept of older adults facing physical challenges, aligning precisely with the criteria outlined in the question.
