Every generation has its own attitudes, values and even quirks. Consider, for example, how different Baby Boomers (those born between 1946 to 1964) are from their parents' generation. No one disputes that the Boomers largely revolted against the morally conservative upbringing of the previous generation. By doing this, Boomers created their own set of values that eventually dominated the culture, including feminism, looser sexual mores and anti-war sentiment. Although the Boomers are one of the more stark examples of generational change, most generations do this to some extent. And the most recent generation to get its own name, the Millennial Generation (born 1980 to about 2000), is no different.
Studying generations is no easy business, however. Dividing and defining people by their birth years can seem like an arbitrary oversimplification. And to some degree, it is. Of course, not every Boomer opposed conservative values. Not everyone from that era fits neatly into the stereotype of a hippie who believed in "free love" and protested the Vietnam War. But generational researchers argue that a shared experience of major events during formidable years, coupled with the shared experience of being raised by a certain generation with its own values, creates a generation with a unique bond and common attitudes.
