How this is built.
Scores are percentiles within our London cohort: your score is relative to other London areas, not absolute. School catchment guidance is powered by School Owl. Crime is from data.police.uk, latest available month.
Family density is drawn from ONS Census 2021 household composition data at LSOA level. We map each postcode to its representative LSOA and rank it against the 32 London postcodes in our cohort.
Commute times are pre-calculated via the TfL Journey Planner API for a weekday arrival at 08:15, from the centre of each postcode to Waterloo, King's Cross, Liverpool Street, Canary Wharf, Paddington and Victoria.
