I'm more interested in the secondary statistic that they gathered, that being that "two-thirds say they couldn’t get by without their parents’ help." That's easier to quantify.

There's a list of what was counted: Health insurance, Home buying/renting, Auto insurance, Utilities, Spending money, Vacations, Large purchases, Online accounts (e.g., Netflix), Taxes

Some could argue that counts as "spending money", but I don't think it would count unless it was a recurring thing.
