The point at which an individual is regarded as an elder varies across contexts. While no single age universally defines this stage of life, it is often associated with eligibility for specific benefits, discounts, or social programs.
The assignment of a specific number to the start of this life phase has historical and societal roots. For example, some government programs were established based on actuarial data and retirement trends. Furthermore, perceived capabilities, shifts in social roles, and changing expectations surrounding work and leisure influence perceptions of when one reaches this life stage.
