Eurostat, the EU’s statistics office, said euro zone output rose by only 0.3 percent during the quarter. That’s down on the previous estimate of 0.4 percent and way below the 1 percent growth recorded in the second quarter.

The revision means that the eurozone grew by half the United States’ 0.6 percent rate and far less than Japan’s 1.1 percent.

The most marked slowdown in growth was seen in Germany.

Though Europe’s biggest economy grew by a still-healthy 0.7 percent during the third quarter, that was only a fraction of the 2.3 percent recorded in the second quarter, when its exports surged on a rebound in global trade.

Lower growth was recorded all round the 16-country single currency bloc but Greece was the only one still in recession — its economy shrank a further 1.3 percent during the quarter, worse than earlier expected.

A more detailed look at the figures suggested that much of the restocking that businesses undertook as they emerged from the recession may have run its course during the third quarter. Gross fixed capital investment, a gauge of business investment, fell by 0.3 percent in the quarter.

The hope among governments, many of which are turning off the support mechanisms introduced during the recession as they grapple with massive debt burdens, is that consumers will start spending more.

However, there’s little evidence that is happening.

Eurostat reported that household consumption during the quarter increased by a muted 0.1 percent, down from the previous estimate of 0.3 percent.

“This, coupled with a lack of any clear visible improvement in the hard labor market data, adds to evidence that the region as a whole may struggle to stage a sustained pick-up in household spending,” said Ben May, European economist at Capital Economics.

As a result of households’ reluctance to spend, the euro zone economy continues to remain reliant on exports, particularly from Germany. Eurostat reported a hefty 1.9 percent increase in exports during the quarter. Much of the impact on growth, however, was negated by a 1.5 percent rise in imports.

In the wider 27-country EU, growth was 0.5 percent, unchanged on the previous estimate but half the rate recorded in the second quarter. The EU as a whole benefited from fairly solid 0.7 percent growth in Britain.

A separate survey showed unemployment in the euro zone in November unchanged at an elevated 10.1 percent, which is the highest level since the middle of 1998. Though the number of jobless fell by 39,000 during the month, this followed hefty increases in the previous two months.

Estonia became the 17th member of the euro zone at the start of 2011.
