An impression – or possibly a fear – that 20-somethings are still hanging about in the family home is based on fact, an influential think-tank has concluded.

The proportion of 25 to 34-year-olds still living with their parents has increased by more than a third in nearly two decades, according to the Institute for Fiscal Studies (IFS).

The living at home trend has been driven by men, and those in their late 20s, researchers found.

High renting costs and rising house prices were the most significant reasons for the change.
