I wonder what the average family income is of Grammar , Modern, Comprehensive, Private and Public Schools are.
Obviously there are FSM indicators but this does not really show anything
regarding average family incomes. FSM percentage does not show the reasons for being on FSM, for instance a pupil at a grammar school could be on it for a short time due to a 'Family Crisis' where as a pupil from a modern school might be trapped for a long time.
What would be interesting if we could find out whether grammar school families on average have twice the income of comprehensive. The other thing that would be interesting would be to find out how much the average 'Public School' family earn.
