About this data

Source: Calculated from ONS, NRS and NISRA births, and ONS, Population estimates for the UK, 1838 to 2025

• This is the crude birth rate: births divided by the mid-year population. Unlike the fertility rate, it depends on the population's age structure, so it is lower when a larger share of people are past childbearing age.
• The UK rate starts in 1912: before then, the UK's population estimates include all of Ireland.
