The difficulty of finding a job and working in poorly paid positions are among the main reasons preventing 25- to 30-year-olds from moving out of the family home, according to the results of a study published yesterday. The survey, conducted by Athens University, showed that two in three respondents, or 68 percent, in the above age group were staying at home for purely financial reasons. Roughly one in four wage earners in Greece earn a monthly salary of just 500 to 700 euros. Greece also has one of the highest unemployment rates in the European Union, with persons under the age of 30 affected in particular. Despite dropping in August to 7.6 percent from 8.6 percent the previous month, Greece’s jobless rate was the second highest in the eurozone.
