You need studies to demonstrate these effects in a scientific manner so yes/no as it could be done by a scholastic institution if it wasn’t done by think tanks.

Demography is moving away from generational studies because aside from Boomers they do not indicate much

Worth noting that Douglas Copeland who wrote the book Generation X that gives the generation it’s name cut it off in 1974 if I recall correctly.

Pew and a bunch of other think tanks are moving past generational studies as it seems that you are correct that you have more in common with people within 5 years of your age than people in your “generation”.

The catch is you usually know more of your ancestors. For example my descendants are two people whereas I know a few dozen ancestors.

Because the baby boom that created the boomers was an actual generational cohort that shared a TON of similarities and had a huge impact as being the largest slice of the male population as so many died in the two World Wars. That lead demographers into thinking all generations worked like this and it took time to have other generations to compare them to.

Pew just announced recently they are moving away from generational cohorts because while someone born in 1979 is technically gen x they have a lot more in common with millennials born in 1985 than a fellow gen x er born in 1967
