Unemployment in the eurozone reached 9.4% in June - the highest in 10 years and another sign of the economic slowdown.
The number of jobless grew by 158,000 during the month, taking the total number of unemployed in the area using the euro to 14.9 million.
The figures came as separate data showed that inflation declined more than expected in the eurozone in July.
Consumer prices in the 16-nation area fell a record 0.6% compared to a year earlier, according to Eurostat.
The BBC reports it was the second month in a row of falling prices following June's decline of 0.1%.
Eurostat has calculated that 3.17 million people living in the eurozone have become unemployed since June 2008, when the unemployment rate was 7.5%.
