Which group is included in the definition of "elderly person"?

The definition of "elderly person" commonly includes individuals aged 60 or older because this age threshold has been widely accepted in both social services and legal contexts. This standard reflects societal views on aging and the associated needs for support and services that often arise at this stage in life. Establishing an age threshold helps define eligibility for various programs, benefits, and resources aimed at assisting older adults.

The other options illustrate different aspects of aging or health but do not align with the broader, widely recognized definition of "elderly." For instance, the age of 55 is generally considered too young to categorize individuals as elderly in most contexts, while references to specific conditions like impairments or retirement do not consistently define the entire elderly population. The inclusion of age 65 is often relevant to retirement benefits rather than the broader classification of elderly, emphasizing the validity of the 60 or older benchmark.
