John Hussman summarizes quite well the scale and breadth of economic decline in recent months: 
"With industrial production, capacity utilization, 
real  disposable income, real personal consumption, real sales retail 
and food  service sales, and real manufacturing and trade sales 
uniformly declining in  their latest reports, coincident economic 
indicators – having generally peaked  in July – are now following 
through on the weakness that we’ve persistently  observed in leading 
economic measures. We continue to believe that the U.S.  economy joined a
 global economic downturn during the third quarter of this  year.
"While we use a broad range of signal extraction 
and  noise-reduction methods in our own work, the economic data in 
recent months has  required less and less sophisticated analysis, as 
many of the most reliable  leading economic measures have turned clearly
 lower (e.g. Philly Fed Index,  Chicago Fed National Activity Index, and
 the new orders and order backlog  components of numerous regional and 
national Federal Reserve and purchasing  managers surveys)." -- John Hussman, PhD. Dec. 4, 2012
