Migration to and from London
Migration in and out of London over time (2008/09 - 2017/18)
Net migration plays a relatively small role in explaining the increase in population seen in London over the last decade. In fact, net migration reduced the overall population of London by more 23,120 in 2016/17, as more people left London than moved to London.
Net migration into London from the rest of the UK and overseas has fallen from nearly 50,000 people a year in 2014/15 to under 10,000 in 2017/18. This is mostly the result of more people moving from London to the rest of the UK and fewer people coming to London from abroad.
More people leave London for the rest of the UK than move from other places in the country to the capital (over 103,000 more in 2017/18) whereas more people come from abroad to live in London than emigrate internationally from the city (113,000 more in 2017/18). This has remained true for over a decade.
Other indicators on the London's Poverty Profile show that the fact that there are far more births than deaths in London each year (over 70,000 more births than deaths in 2018) is the main contributor to London’s increasing population.
