Joblessness in the 17 country bloc was 11.4 percent of the working population in August, stable compared to July on a statistical basis, but with another 34,000 people finding themselves out of work in the month, the EU's statistics office Eurostat said. It was 16th straight monthly rise.

That left 18.2 million people unemployed in the euro zone, the highest level since the euro's inception in 1999 and a rise of some 2.6 million people since early 2011. Around 25.5 million people were out of a job in the wider 27-nation European Union.

"It is clearly unacceptable that 25 million Europeans are out of work," European Commission spokesman Jonathan Todd told a regular briefing. In a separate statement, the EU executive said the data showing a record 22.7 percent of 18-to-25-year-olds out of work in Europe in August was of real concern.

"EU institutions and governments, businesses and social partners at all levels need to do all they can to avoid a lost generation, which would be an economic and social disaster," the Commission said.
