1. Hospital catchment populations are estimated based on the proportion of children and young people (≤18 years) from each LSOA who attend each NHS Trust in any given year for planned or unplanned care. See Methods section for full details.
2. Although all Trust are presented for completeness, the catchment population is more meaningful and useful when applied to Trusts that provide general paediatric services than to specialist Trusts (for example, Moorfields Eye Hospital, Great Ormond Street Hospital, The Royal Marsden Hospital, The Royal National Orthopaedic Hospital).
3. Where large changes occur between years, this typically reflects mergers or reconfiguration. For example, during the study period, Barnet and Chase Farm Hospitals NHS Trust merged with Royal Free Hampstead NHS Trust and there was extensive reconfiguration of services in North West London (North-West London Hospitals NHS Trust, Ealing Hospital NHS Trust and London North West Healthcare NHS Trust).
4. *Denotes Trusts where LSOA data are missing on ≥5.0% of hospital admissions (meaning that the catchment populations should be interpreted with more caution). The exact proportion of admissions with missing LSOA data in each Trust are presented in online supplementary appendix table A5.
