Thanks to @beckybose
on Twitter for alerting us to this article
about the locations of new free schools.
It explains "the average property asking prices in the areas around the new Free Schools are £126,430 more (or 57.5%) than the UK average (currently £219,513)."
Two of the new schools (ARK Conway Primary Academy and St Luke’s Church of England Primary School) are surrounded by property worth over £1,000,000 on average, both of which are in London.
This may explain the relatively low FSM figures thrown up by School Duggery's investigation
into the social make up of these new schools.
