Greece's jobless rate dropped to 18% in December from a downwardly revised 18.3% in the previous month, data from the country's statistics service ELSTAT showed today.
December's unemployment rate was the lowest reading since July 2011.
Seasonally adjusted data showed the number of unemployed at 851,556 people, with younger persons aged up to 24 bearing the brunt of being out of work.
Among younger persons aged 15 to 24, the jobless rate fell to 39.5% from 43.1% in the same month in 2017.
Greece's jobless rate, which hit a record high of 27.8% in September 2013, has been coming down since but remains the highest in the euro zone.
The government expects unemployment to decline to 18.2% this year as the economy recovers, based on projections in its 2019 budget.
Greece's economy shrank slightly in October-to-December after expanding for nine consecutive quarters.
