US consumer sentiment index rises to highest level since 2004, many expect further gains

U.S. consumers are more confident than they've been since January 2004.

The University of Michigan says that its index of consumer sentiment rose to 98.1 in January from 93.6 last month.

Consumers say the prospects for the U.S. economy are the strongest in a decade, and half of consumers expect the expansion to keep going another five years.

The Michigan survey was the latest evidence that strong job growth and tumbling oil prices have lifted consumers' spirits. The Conference Board on Tuesday reported that its consumer confidence index climbed to the highest level since August 2007. And the Commerce Department reported Friday that consumer spending rose from October through December at the fastest pace in nearly nine years.
