Engaging Diverse Voices through Research & Resources

Key Definitions

Age

“In everyday life, people are divided into age categories such as children, youth, adults, and seniors. Each of these groupings has its own schema of appropriate behavior or attributes and is associated with a corresponding set of social relationships with other people and with institutions like the education system, the labor market, and the state. The process of human aging involves passing through a sequence of age-based stages across the life span and socializing into implicit and explicit roles associated with each of these stages. ... To illustrate the complexity of the concept of aging, it is useful to differentiate between different types or meanings of age:

  • Biological or physiological age refers to the physical aging of the human body.
  • Chronological age represents the amount of time that has passed from the date of birth.
  • Psychological age stands for age-related adaption capacities of an individual.
  • Social age signifies norms, behavior, and attitudes conceived as appropriate for an age group.”

Keyword Suggestions

Keep in mind that some words that were commonly used in the past have since become outdated or even offensive. You may encounter these outdated terms in your research, and you may even need to use them in your own searches in order to get a complete view of your topic, especially if your topic is historical in nature. However, please be careful about using these words yourself, especially if you do not identify as part of the community that you are researching.

Terms marked with an asterisk (*) are considered offensive by some people and should only be used for self-identifying or quoting someone who explicitly self-identifies using that term.
