Not the prettiest graph, but a neat way of putting all this information into one image.

Isn’t it a bit arbitrary to just divide time into generations like this? It makes more sense for big events in history, like the world wars, but now, I don’t know. According to this I am a millennial, but what does that mean really? That I saw the internet become what it is now? Not a very defining thing for a whole generation imho.
Generations are divided like that, at least some of them.
Boomers for example, refers to the population boom after WW2 and millennials refer to people who generally came into adulthood around the widespread adoption of the internet.
Generally though, generations are divided into cohorts and they do have arbitrary cutoff points. Generally the goal isn’t to say “this group of people experienced x event” it’s just meant to say that the general cohort had similar over arching experiences in society.
That’s also why there are mixed definitions, and over lapping time periods, because not everyone identifies perfectly with their cohort.
Yes, incredibly arbitrary, and yet that doesn’t stop people immediately grabbing on to them for whatever tribalism they want to justify. The “baby boom” was a notable thing where suddenly there were a lot of post-war births, the rest is at best some vague suggestions that these people sort of behave similarly because of similar geopolitical conditions.
