An "age group" refers to a specific range of ages that share common characteristics or experiences. These groups are often used in research, marketing, and social studies to analyze behaviors, preferences, and needs. For example, children aged 5-12 may be grouped together to study their educational needs, while teenagers aged 13-19 might be examined for trends in social media usage. Age groups can also influence cultural and social dynamics. For instance, baby boomers (born approximately 1946-1964) may have different values and lifestyles compared to millennials (born approximately 1981-1996). Understanding these differences helps organizations tailor their approaches to various demographics effectively.
