Some 1.97 million adults aged between 20 and 34-years-old are still living with their parents, according to a major housing charity.
Shelter said data collected during the last Census showed nearly 2m adults in England were still living with mum and dad and urged the Government to do more to help the "clipped wing generation" finally fly the nest.
A survey commissioned by the charity also found that nearly half (48%) of 250 young adults who live with their parents said they do so because they cannot afford to rent or buy their own home.
The Census also showed the number of grown up children still living with their parents varied between different parts of England.
