Nearly two million young adults in England are still living with their parents because of the cost of housing, a report from Shelter has found.
Some 1.97 million workers aged between 20 and 34 are living with their families as high prices and rents and poor wage growth are making it unaffordable for them to move out.
Some 48% of the 'clipped-wing generation' blamed their situation on the fact they cannot afford to live by themselves, while more than half (52%) said living at home was preventing them from living fully independent lives, the housing charity reported.
Nearly a third (32%) said they were living at home as they wanted to save for a deposit or a mortgage for their own home, while just 27% said they were happy to live with their parents.
Hotspots for the young living at home include Castle Point in Essex, which has 45% of its 20-34 year olds living at home, while the county's Rochford area has 42% still living with their parents.
London has the lowest percentage of young adults living at home at 21%.
Campbell Robb, Shelter's chief executive, said more needs to be done to solve the UK's housing crisis.
He said: "The 'clipped-wing generation' are finding themselves with no choice but to remain living with mum and dad well into adulthood, as they struggle to find a home of their own.
"Rather than pumping more money into schemes like Help to Buy, we need bolder action that will meet the demand for affordable homes and not inflate prices further."
Figures from the Land Registry this week revealed that the average UK house price in June stood at £172,011 – a rise of 6.4% on prices last June.
