You asked
I am searching for statistics on the proportion of London residents who were born in the city. There is a lot of research on foreign-born populations, but I cannot find anything that takes into account internal migration.
Are any figures available?
We said
While we do produce internal migration estimates, unfortunately we do not do so by place of birth so are unable to provide the figures you request.
