Generations refer to groups of people born around the same time, typically spanning about 20 to 30 years. Each generation shares unique experiences, values, and cultural influences that shape their perspectives. Commonly recognized generations include the Baby Boomers, Generation X, Millennials, and Generation Z. The study of generations helps sociologists and marketers understand trends in behavior, technology use, and social attitudes. For example, Millennials are known for their comfort with technology, while Baby Boomers may prioritize traditional communication methods. Understanding these differences can aid in effective communication and engagement across age groups.
