The association has been surveying the living conditions for young people since 1997, and says that the number of youngsters living at home with their parents has risen from 15 to 22 percent over the last 14 years. Many of the others are forced to either sub-let or share with friends.
Ylva Westander was in charge of the report, and says that forcing young people to stay at home can make life difficult for them.
"Living with your parents means you can't act like an adult", she says, "and there is a big insecurity among those that are living in the more insecure tenure forms because they can't plan their economy, and they can't plan their lives like most people want to do. If you don't know where you are going to live in half a year, or even just two months, you can't really plan anything else either."
Westander says the reason for the lack of affordable housing for the young in Sweden is due to a lack of political initiative, and a lack of initiative from building companies.
"Young people don't have the same economy as older people and they need cheaper housing, and there is a lack of cheaper housing in mostly the urban areas."
