The number of people leaving London has jumped more than 80 per cent in the past five years, with more than 93,000 people departing the capital last year, figures have suggested.

Research by Savills shows the exodus is being led by those in their 30s, with the number of those between the ages of 30 and 39 leaving the capital rising 68 per cent between 2012 and 2016, to 34,540.

That was followed by those in their 50s, with a 46 per cent rise in departures, while the number of people in their 40s leaving rose 43 per cent.

In fact, the only group where the figure rose was those in their 20s, where the number of people leaving London fell nine per cent between 2012 and 2016.

The figures suggested (not surprisingly) the main driver for those leaving the capital is the average house price: the average sale price in London is £579,836, while the average price for those buying outside the capital is £333,181. That’s a difference of almost £250,000.

That said, the largest portion of people leaving London tend to head to places less than 25 miles away, where house prices average out at £481,436.

Earlier this month we analysed ONS internal migration data, and found the majority of those leaving London last year headed to Birmingham, where the average house price is £132,000.

That was followed by Brighton, Thurrock and Epping Forest, as well as Medway and Dartford.

And back in 2015, a YouGov survey suggested Londoners were surprisingly keen to live elsewhere, with 36 per cent saying they wanted to move out of the capital, while 52 per cent said living in London was “stressful” – although another 44 per cent said they were comfortable.
