London is widely known for being a city of immigrants – famously, a third of its residents were born abroad. It’s not quite so well-known as a city of emigrants. But, at least within the UK, that is its role.
According to internal migration data recently released by the Office for National Statistics, London sees by far the greatest population loss of all the English regions. 242,000 people moved out of London in 2011. When offset against those moving to the capital, this resulted in a net loss of 40,000 people.
