The real national debt

FiveThirtyEight: Politics Done Right: "Per-family household debt increased by about 130% in real dollars between 1989 and 2007, from roughly $42,000 per family in 1989 to $97,000 eighteen years later. Most of that increase has come during the past six or seven years -- household debt increased by 52% between 2001 and 2007 alone."
