NEW YORK — Americans are feeling worse about the economy than they have in a long time – a fact that could have wide-reaching implications.

Despite improving U.S. job and housing markets, consumer confidence fell to the lowest level since November 2011, according to The Conference Board, a private research group. The results are the latest swing in the index, which has been on a rollercoaster ride

The index declined in January, rose in February and then posted four months of declines before registering an increase in July. August’s reading indicates that the gains in the job and housing markets aren’t big enough to put to rest Americans’ economic fears.
