But it's all artificial, the invention of some pop sociologist to make money.
Actually the designation of generations goes back to, well...the bible.
It is a legitimate form of analysis. The names that are designated have become more hip over the past fifteen years or so.
Generally speaking a generation is about 22 years. That was defined as the amount of time to go from being born, to the median age of producing another generation. So the boomers went from 44-65, X’ers are from 65-86, and so on and so forth.
Doing some studies on generations following WWI and the Civil War will give you some insight as to why things are going the way they are. If you think about it, the garbage we went through in the 20’s and 30’s closely resembles what is happening today....a few short years after the end of the Cold War.
Doesn’t make the next ten years look good.
