Consumer spending fell by 0.3%, marking the largest decrease since 2009. The Gross Domestic Product (GDP) report showed that the economy grew at 2.6% in 2014, but consumer spending still fell as a result of low gas prices and a milder winter. Consumer spending accounts for two thirds of U.S. economic activity.
