Household net worth drops 36% in six years.

The median net worth of American households dropped to $69,000 in 2011 from $82,000 in 2000 and $107,000 in 2005, a census report shows. Meanwhile, debt in households headed by older people more than doubled during the decade to a median $26,000 from $12,000, largely because of mortgage loans. The trend increases worries about the financial well-being of older Americans, whose retirement funds have been hit by the recession and rock-bottom interest rates.
