WASHINGTON - The burst of energy the economy showed at the end of last year isn't likely to be repeated anytime soon.
The Commerce Department reported Friday that the economy grew at a 5.6 percent pace in the October-to-December quarter in its third and final estimate of economic activity during the period.
Even though growth turned out to be a tad less than the government's prior two estimates for the quarter, the new reading still marked the strongest showing in six years.
Many economists, however, think the economy has slowed in the current quarter to about half the pace seen at the end of last year.
Why won't the big growth spurt be repeated? Because the main force behind it is already ebbing.
Most of last quarter's growth came from a large bump up in manufacturing - but not because consumer demand was especially strong.
In fact, consumer spending weakened at the end of the year, even more than the government previously estimated, contributing to the slightly lower reading on overall economic growth.
Instead, factories were churning out goods for businesses that had let their stockpiles dwindle to save cash.
If consumer spending remains lackluster as expected, that burst of manufacturing - and its contribution to economic activity - will fade.
Analysts predict the economy will expand at only between a 2.5 percent and 3 percent pace in the first quarter of this year. The next two quarters should log similar growth, they say.
In normal times, growth in the 3 percent range would be considered respectable. But the nation is emerging from the worst recession since the 1930s.
Sizzling growth in the 5 percent range would be needed for an entire year to drive down the unemployment rate, now 9.7 percent, by just 1 percentage point.
