WASHINGTON (AP) U.S. consumer spending slipped in December, as the pace of motor vehicle sales slowed and more Americans saved their money.

The Commerce Department said Monday that consumer spending fell 0.3 percent in December, compared to a 0.5 percent increase in November. Cheaper gasoline and fewer auto sales accounted for most of the decline. Energy prices tumbled 5.2 percent in December for the sixth straight monthly decline.Personal income rose 0.3 percent in December, aided by the steady wave of hiring over the past year. But rather than spend those gains, consumers saved 4.9 percent of their disposable income, up from 4.3 percent in November.Despite the decrease, several indicators show that Americans are growing more comfortable about the economy and are spending money again."Further big real income gains and soaring confidence point to serious strength in spending," said Ian Shepherdson, chief economist at Pantheon Macroeconomics. "(W)e would not be surprised to see gains approaching 5 percent annualized in the spring."Consumer spending rose at an annual clip of 4.3 percent during the final three months of 2014, the strongest pace since early 2006, the government reported Friday. That surge helped drive overall economic growth of 2.6 percent, as roughly 70 percent of gross domestic product stems from consumer activity.The University of Michigan reported that its consumer sentiment index stood at 98.1 percent in January, the highest reading since 2004. Half of the consumers surveyed expect the current expansion to continue for the next five years.
