BBC article
here comparing percentage of household expenses on various areas between 1957 and 2006.
Going Down:
Food spending has halved
Fuel/Power has halved
Clothing has halved
Tobacco is now a sixth of what it was
Going Up:
Housing has doubled
Transport has doubled
The Same:
Alcohol
What's particularly interesting is that between them, those items made up 75% of spending in 1957, but only 62% nowadays. Meaning that we have an extra 13% being spent on other things.
Not that it's made us any happier - people are pretty much exactly as happy as they were in 1957.
The ownership graph at the bottom is also fascinating. Of the poorest 10th of society, 31% have a computer, 21% have the internet, 56% have a mobile and 50% have satellite/cable TV.
