Human Populations Are Not Quantised!
> Boomers don't look up things they don't know
Ah, "Boomer", another one of those terms that gets bandied about without checking that it means the same thing to the reader as it did to the writer (you know, the sort of thing that this entire article is talking about!)
Since I were a nipper in the UK, The Baby Boom has meant the rise in births in 1946, straight after the war, which caused significant extra (given that rationing was still in place, etc) social upheaval. For example, having to build new schools and find adequate numbers of teachers in order to keep up with the cohort as it aged. Schools that were then in danger of being underutilised the following year and more so the next, as the boom was a definite spike: by 1947 proper British values had set in (and absolutely everyone had been reminded about the joys of baby sick and wailing at all hours of the day) so things pretty much settled down again to the usual pace.
Those Brits are all 76/77 years old now. A strangely specific group of people to be targeting with respect to their abilities with respect to dictionaries, encyclopaedias and the like.
However, apparently, the US just kept on at it, from 1946 all the way to 1964 (presumably the more greatly spread out population meant they were less troubled by the wailing from up and down the street in 1947 and then it all just became a habit). So they have a lot more "Baby Boomers" with a far wider age spread.
Can I take it that it is Our Overseas Cousins you are referring to and whose inability to use reference materials is in question?
BTW According to Wikipedia, "British people usually define" those born between 1960 and 1969 as Baby Boomers! First I'd heard of it! This claim is backed up by Wikipedia using a link to a single paper from 2017 in the journal "Working With Older People" (which, as you know, is one of the great trend setters in British culture), which paper uses the term pretty much just "because we want a catchy readable title" not because it is usual! Wikipedia then goes on to claim that this ten-year cohort makes up 20% of the UK population, because the Wikipediots have referred to an "article" on yougov.co.uk which was nothing more than a headline ripped from another article that clearly stated it was using the US "definition" of "Baby Boomer"!
Sigh. Rant nearly over, conclusions:
* Wikipediots don't even bother reading the material they link to
and
* these "generations" only refer to the US, at least up to the point where t'Internet has tried to homogenise culture (that would be "Z", I guess). So it has been weird looking up what all these supposed generations[1] mean in order to follow a Register article about results from a UK survey!
[1] In my day we didn't have these fixed so-called "generations", we knew that babies are being born all the time, so "my parent's generation" meant something different to different people. Human Populations Are Not Quantised!
