Following are time frames that have been coined for people based on the year they were born. There are differing opinions regarding the dates, and there is overlap.
Baby Boomers - 1946 to 1964
More than 76 million baby boomers were born between 1946 and 1964 in the U.S. Older baby boomers were raised without desktop computers, and many did not even have TVs as children.
Generation X - Mid-1960s to Early 1980s
The name was coined as a result of a study of young people's attitudes in England in 1964 by Jane Deverson. The gen X period saw the rise of hippies and countercultures across the Western world. By the time older gen-X'ers became teenagers, the personal computer revolution had begun.
Generation Y - Early 1980s to Early 2000s
In Western cultures, gen Y'ers, also known as "Millennials," were brought up in the age of personal computers and electronic gadgets.
Generation Z - Mid-1990s to Early 2010s
Also called the "Net Generation," these individuals were exposed as children to the Internet along with wireless and mobile technologies and social networking. Gen Z'ers take electronic wizardry for granted.
iPhone Generation - After 2008
