WASHINGTON, Oct 31 (Reuters) - The U.S. economy grew at a surprisingly brisk clip in the third quarter, the government said on Wednesday in one of a series of reports that implied a resilient expansion despite a battered housing sector.

Strong consumer spending and brisk exports helped push gross domestic product ahead at its fastest rate during the third quarter since the beginning of 2006, while there also were signs private employers were still building up payrolls.

GDP measures total production within U.S. borders. It grew at a 3.9 percent annual rate in the July-September quarter, up from 3.8 percent in the second quarter. It was the strongest growth since 4.8 percent in the first quarter of 2006.

Federal Reserve policy-makers still were expected to cut interest rates a quarter percentage point at the conclusion of a two-day meeting on Wednesday notwithstanding the GDP data that showed a strong economy in the summer.

"For the FOMC members, it really says that conditions did not deteriorate even though housing continues to crash," said economist Joel Naroff of Naroff Economic Advisors in Holland, Pa., but it won't preclude "taking out a little more insurance" in a rate cut to forestall a future housing-induced slowdown.

The GDP report showed that spending on housing construction declined for a seventh straight quarter. A separate Commerce Department report issued later -- on September construction spending -- said total spending was up 0.3 percent in September but residential spending slumped for a 19th straight month.

WORRIED, BUT STILL SPENDING
