Sorry I don't really have any good links, my knowledge on demographics comes from working in the news/TV industry and attending a lot of marketing meetings.
Anyway it makes logical sense though when you think about it, and there is plenty of evidence if you watch TV or open magazine. But here is an overview:
The school age people, although highly influenceable don't have spare cash mainly because they don't have a job (or just a part time job). So thats roughly your 15-25 group, you can sell them cheaper more fashionable items. Music has always been a real winner here because its cheap and fashionable.
The next major bracket is 25-35, people who have there first jobs, no real debts, and are trying to settle down or impress others. You can't really sell big ticket items here because they are often saving for a house or something, but medium range stuff you can.
between 35-50 its a wasteland, people have priorities that trump marketing, kids, mortgages etc... You won't see a lot of advertising targeted to this group unless its to do with kids or household items. Car manufacturers target this bracket a bit I think, but really its to much of a hard sell when there is easy money else where.
The next group is the 50-65, these people who suddenly have there lives back. Not a hugely impressionable group but will really splash out on the big ticket items. New cars, expensive holidays, this is where the real money is. Need a computer? buy something top of the line.
I remember hearing 45-55 chucked around a lot in meetings, this would be the mid life crisis bracket. More or less the same bracket as the 50-65 but I guess more impressionable due to the fear of getting old.
65+ it changes again because health starts to become an issue. Priorities start to trump.
So theres only two demographics with money 25-35, and 50-65. With the 50-65 being the real spenders.
Apple historical has had a majority 50+ user base, but recently has started selling very well in the 25-35 bracket. Co-incidence? I think not.
Heres one I found in a quick google: https://www.aarpglobalnetwork.org/netzine/TrendWatch/northam... but TBH you might as well search the topic yourself if you have a real interest.
