Greeks are on average almost 40% poorer than they were in 2008, data indicated today.
The figures laid bare the impact of a brutal recession and austerity measures the government may be forced to extend into next year.
Gross disposable incomes fell 29.5% between the second quarters of 2008 and 2013, statistics service ELSTAT said today. Adding in cumulative consumer price inflation over the same time takes the decline close to 40%.
Propped up by international aid since 2010, Greece is at loggerheads with its lenders from the European Union and International Monetary Fund over the size of its 2014 budget deficit.
The discrepancy has prompted talk that Athens - which has ruled out across-the-board cuts in wages or pensions - migh thave to adopt new austerity measures.
Spending cuts and tax hikes to meet the terms of its international bailouts, coupled with record unemployment, have eroded domestic consumption, which in Greece accounts for about three-quarters of gross domestic product, the biggest proportion of the 17 countries in the euro zone.
Total workers' compensation has fallen 34% since the second quarter of 2009, the ELSTAT data showed. Over the same time, the government slashed social benefits by 26%.
The statistics service said the deep economic malaise also affected household savings rates, which fell 8.7% in the second quarter of 2013 compared to a 6.7% drop a year earlier.
Based on EU/IMF projections, Greece's battered economy is expected to contract 4% this year before recovering modestly in 2014. This would bring the total GDP decline in 2008-2013 to 25% - making it the country's longest peace-time recession.
