Figures are aggregates over the public planning decisions we hold for Westminster, matched to a project type from the application description. Overall approval is decided-weighted across project types, using each type's rate over the last 5 years where we hold enough decisions, otherwise its full record. Only types with at least five decided applications are shown. We publish aggregate counts only, with no application references or applicant names. Full method and limits.
