What i defined as Generation X stands,your just confused because of one thing.Sometimes people can't decide when a generation ends,this is a "cusp" people born in certain years can call themselfs one generation or another or their own small generation.
This has happened with the World War 2 Genration and the Baby Boomers.Those who were too young to fight in World War 2 can sometimes be called baby boomers,because everyone agrees that the boom started in 1946,the year when American soilders becan to go home.But what about children born in 1945 or before?Where do they go?
That's what i mean,people who are inbetween generations.The second cusp happens in the baby boom.American birth rates show the bomb declining in 1957,raw facts say this year was the last year of the boom.Yet there were children born afterword,these children came before Generation X of the 1970's,children of the baby boomers.
Inbetween,it's complicated because some sites can say these years are this generation..and other sites could say those same years are of another generation.
