According to the St Louis Fed, America is at about 69%. (The figures on younger buyers -- under 35 years old -- from '95 to '04 are interesting.) Ireland, according to the same report, comes in at a whopping 80%.
I'd be interested to know how these figures stack up against household debt.

That chart seems to support it. Conservatives want live babies so they can raise them to be dead soldiers. - George Carlin
