U.S. gasoline demand fell last week from a year earlier as pump prices stayed above $3 a gallon, a report from MasterCard Inc. showed.

Consumers purchased an average 9.3 million barrels of gasoline a day in the week ended Dec. 7, down 2.7 percent from the same week last year, MasterCard, the second-biggest credit-card company, said in its weekly SpendingPulse report. Demand fell 0.9 percent from the previous week.

The national average pump price for regular gasoline fell 6 cents to $3.03 a gallon, the report showed. The price was 32 percent higher than a year earlier.

The report from MasterCard, assembled by MasterCard Advisors, the company's consulting arm, was based on credit-card swipes and cash and check payments at about 140,000 U.S. gasoline stations.

The U.S. Energy Department estimated demand of 9.27 million barrels a day for the week ended Nov. 30. MasterCard, based in Purchase, N.Y., said demand was 9.39 million barrels a day for the same period. The government's next petroleum report is set for release today.

The Energy Department calculates demand through the amount of fuel drawn from refineries, terminals, pipelines, blenders and importers.
