A "generation" refers to a group of individuals born and living around the same time, typically spanning about 20 to 30 years. This concept helps sociologists and historians categorize people based on shared experiences, cultural influences, and historical events. For example, the Baby Boomers were born post-World War II, while Generation X followed them, experiencing different societal changes. Generations can also influence trends in technology, fashion, and values. Each generation often has distinct characteristics shaped by the time they grew up in. For instance, Millennials are known for their comfort with digital technology, while Generation Z is recognized for their activism and social awareness.
