I can remember having to mow the lawn if I wanted my $5 allowance. Things have changed. From It Doesn’t Grow On Trees:
In 2002, teens accounted for more than $170 billion in spending, an increase of 38 percent from five years ago. Teens spend an average of $92 per week, and most receive money on an as-needed basis from their parents as opposed to getting a strict, defined allowance.

Allowances have been rising at nearly twice the rate of inflation with the average allowance for a child today being $11.79 per week.
