Gen-X here. However, I have an issue with their thresholds for Gen-X, Millennials, and Gen-Z.
For the longest time, Gen-X was always 1965-1983. But around the time of the Great Recession, they started shrinking it, and then moving the Millennials down a few years. I'm convinced they did that, so they could start with those news stories about how bad Millennials in the workforce were getting affected by the Great Recession. If they had the Millennials start at 1984, that means the oldest ones would have only been 24, and not that many in the workforce yet. Most of them were still in college, high school, or middle/elementary school! But, take a few years off of Gen-X, and give it to the Millennials, and suddenly you have a lot more workers to pull your stats from!
Or, is it just the norm to shrink the more recent generations to 16 years? In all fairness, those earlier generations weren't the same length, either. I guess I just think of 19 years as the default, because that's what the Baby Boomers are, and it seems like that was the generation when the government and media and such started paying attention to these generations.
In more recent years, I've thought of Gen-X as more like 1965-82, Millennials as 1983-2000, and then 2001 and up I just sort of lump them together.
But, regardless, was born in 1970, so I'm still gen-X, no matter how they fiddle with the end-points. As for the Baby Boomers, I'd have to agree on a split, somewhere. Someone born in 1946 could have been off fighting in the Vietnam War, while at the same time someone born in 1964 was probably watching "Gomer Pyle: USMC."
I think Gen-X has a break point, too. The older ones remember a time before video games and home computers, and a lot of us outgrew home video games, thanks to the "Great Video Game Crash" of 1984. We got tired of our Atari VCSs, Odyssey2s, Intellivisions. and ColecoVisions. But then the younger ones only have a faint memory of those early systems, and were raised on Nintendo and then Sega Genesis. And, even other things, like the older Gen-X, when they got a hand-me-down car from their parents, were probably accustomed to having to pump the gas pedal before starting, and putting on snow tires in the winter, whereas the younger ones were more likely to get a car that was fuel injected, with all-season radials.
But, all generations have nuances like that within them.
