These data show the percentage of pupils at state funded schools who live more than 2 miles from school (for those aged under 8) or 3 miles from school (for those aged over 8), 2018.
Warning: These data are taken from analysis used to create the GLA London Schools Atlas which is based on data from the DfE National Pupil Database. These rates are taken from the variable 'SC_Pupil.DistCurrSch - Distance in miles from pupil postcode to current school'. This is not exactly the same as the nearest walking distance used for eligibility for local authority funding for free travel to school.
