About this data

Source: NHS England, NHS Maternity Statistics; Public Health Scotland, Births in Scotland; Welsh Government, Maternity and birth statistics; Public Health Agency, Children's Health in Northern Ireland

• Each nation publishes its own figures, counting slightly differently: England counts deliveries, Scotland live births of single babies, and Wales and Northern Ireland all births. The differences are small, at most about one percentage point.
• Shares are of births or deliveries where the method was recorded.
• Northern Ireland's figure for 2023/24 is the Public Health Agency's estimate, adjusted for missing records after a change of hospital IT system.
