The situation is worst in Stockholm, where an estimated 40,000 people aged 20 to 27, or roughly 58 percent, are forced to live with their parents because they are unable to secure their own home.
"Never before have so many young adults be so dependent on their parents," Karolina Lemoine, an investigator with the Swedish Union of Tenants (Hyresgästföreningen), told the union's own magazine, Hem & Hyra.

The figures come from a survey carried out for the tenants' group by polling firm Skop and are based on interviews with more than 4,000 people carried out earlier in the year.
The results, compiled in a report authored by Lemione and entitled How young adults live 2013? (Hur bor unga vuxna 2013?), show that the percentage of young people who have succeeded in finding their own place to live is the lowest since measurements began a decade ago.
The report also shows that nearly one out of four young adults in the Gothenburg region still live with their parents, and that 65 percent, or 20,100, would rather be living on their own.

In Malmö and Lund, one in five young adults still live at home, with 56 percent, or 6,300, reporting they'd prefer to be living on their own.
"Housing construction had dropped at the same time that the population has risen in larger cities. Politicians have abdicated their responsibilities in favour of the market when it comes to housing," said Lemoine.
