The preliminary reading of the Thomson Reuters/University of Michigan overall index of consumer sentiment stood at 81.2, unchanged from the final reading in January. Analysts polled by Reuters expected a February reading of 80.6.
The survey's barometer of current economic conditions slipped to 94.0 from 96.8 in January, below economists' forecast of 95.9. But the consumer expectations gauge rose to a six-month high of 73.0 from 71.2, comfortably beating a 71.6 forecast.
Economists suspect extreme cold and heavy snowfall in the Midwestern and eastern United States this winter have suppressed hiring and consumer spending, making it harder to gauge the underlying strength of the economy.
The survey's one-year inflation expectation rose to 3.3 percent, a five-month high, compared to 3.1 percent in January. The five-to-10-year inflation outlook held steady at 2.9 percent.
