The big change is that a lot more people stay in London when they have children, rather than moving out which a lot used to do. Partly in response to the quality of schools, which in some areas were the reasons for departure. A lot of this can probably be put down to the increased interest in living in cities and money going into a broad range of facilities, access to arts and culture, jobs etc over the past decade or so.

It is the opposite of the problem in the 1980's/1990's when Councils were closing schools, particularly at Secondary level because there just weren't the children around for them.

It is an issue across the whole of South London (and probably other parts too) and particularly the areas that Estate Agents say are very family friendly e.g. Forest Hill, Herne Hill, East Dulwich....
