One in six, or 61.2 percent of Italians between the age of 18 and 34 still lived at home in 2012, 31,000 more than in the previous year.
Those still with their parents are mostly single who can’t afford to live alone or are forced to return home, the agency said.
Men also make up the bigger proportion, with Istat figures from late last year showing that 52.3 percent of men aged 25-34 were living with their parents compared to 35 percent of women.
The figures are hardly surprising seeing jobless rates are at a record high of 12.7 percent and unemployment among 15 to 24-year-old stands at 41.6 percent.
High rents and bleak prospects of property ownership also mean more young Italians are forced to stay home for longer.
