Net population change in London (2008/09 - 2017/18)

Each year, the number of births in London significantly outweighs the number of deaths. For example, over the last five years, there were around 4.1 times more births in London than deaths.

This means that natural population change (births minus deaths) is consistently a much greater contributor to population growth in London than migration. 

For example, in 2017/18, there were 73,000 more births than deaths in London whilst net migration was only 10,000. Over the last five years, natural population change has increased London’s population by close to 400,000, or 80.5% of the total increase in population. In contrast, net migration contributed less than 100,000 (19.4% of the increase in population).
