• Causes are grouped by ONS's cause groups for infant deaths, which assign each death one main cause from the death certificate.
• 'Pre-term birth' covers conditions related to being born too early, such as breathing problems and bleeding in the brain in babies born very preterm. 'Congenital anomalies' are conditions present from birth, such as heart defects and chromosomal conditions. 'Infections in the womb' are infections that began before birth.
• 'Sudden infant death' includes sudden infant death syndrome and other sudden, unexplained deaths.
• Figures are for deaths registered in each year.
