Article Summary Although Growing at Only Half the Average Rate Following the Following

Article Summary
Although growing at only half the average rate following the seven previous recessions, consumer spending has increased 9 percent since the end of the 2007-2009 recession, and consumer confidence has been on the rise as household finances, the job market, and the housing market continue to improve. The Federal Reserve projects a 3% - 3.5% growth rate for the economy in 2014, up from the recent average of 2%. Debt payments have fallen to an average of 15.69% of after-tax income for households, the lowest level in 30 years, and lower debt payments leave households with more to spend on consumer goods.
