The time line represents the generations, is a very subjective to opinion of different sociology scientists, and differ wildly among different countries as it is related to incidents affected the Americas and Europe.
Generations’ properties: 
(Born: 1966-1976 – Coming of Age: 1988-1994 – Age in 2017: 41 to 51)
Sometimes referred to as the “lost” generation, this was the first generation of “latchkey” kids, exposed to lots of daycare and divorce.
Known as the generation with the lowest voting participation rate of any generation, Gen “X”ers were quoted by Newsweek as “the generation that dropped out without ever turning on the news or tuning in to the social issues around them.”
Gen X is often characterized by high levels of skepticism, “what’s in it for me” attitudes and a reputation for some of the worst music to ever gain popularity. Now, moving into adulthood William Morrow (Generations) cited the childhood divorce of many Gen Xers as “one of the most decisive experiences
influencing how Gen Xers will shape their own families”.
Gen Xers are arguably the best educated generation with 29% obtaining a bachelor’s degree or higher (6% higher than the previous cohort). And, with that education and a growing maturity they are starting to form families with a higher level of caution and pragmatism than their parents demonstrated. Concerns
run high over avoiding broken homes, kids growing up without a parent around and financial planning.
(Born: 1977-1994 – Coming of Age: 1998-2006 – Age in 2017: 23 to 40)
The largest cohort since the Baby Boomers, their high numbers reflect their births as that of their parent generation. The last of the Boomer Is and most of the Boomer II s. Gen Y kids are known as incredibly sophisticated, technology wise, immune to most traditional marketing and sales pitches…as they not only
grew up with it all, they’ve seen it all and been exposed to it all since early childhood.
Gen Y members are much more racially and ethnically diverse and they are much more segmented as an audience aided by the rapid expansion in Cable TV channels, satellite radio, the Internet, e-zines, etc.
Gen Y are less brand loyal and the speed of the Internet has led the cohort to be similarly flexible and changing in its fashion, style consciousness and where and how it is communicated with.
Gen Y kids often raised in dual income or single parent families have been more involved in family purchases…everything from groceries to new cars. One in nine Gen Yers has a credit card co-signed by a parent.
(Born: 1995-2012 – Coming of Age: 2013-2020 – Age in 2017: 5-22)
While we don’t know much about Gen Z yet…we know a lot about the environment they are growing up in. This highly diverse environment will make the grade schools of the next generation the most diverse ever. Higher levels of technology will make significant inroads in academics allowing for customized
instruction, data mining of student histories to enable pinpoint diagnostics and remediation or accelerated achievement opportunities.
Gen Z kids will grow up with a highly sophisticated media and computer environment and will be more Internet savvy and expert than their Gen Y forerunners.
