About this data
- Calendar years. Births minus deaths uses births to mothers living in each UK nation and deaths registered in the year; Northern Ireland's 2025 figures are provisional.
- Net migration up to 2011 is from ONS's earlier, survey-based method; from 2012, from its current method, based mainly on administrative data. The two aren't directly comparable. Estimates for 2025 are provisional.
- The two together don't exactly match the change in ONS's mid-year population estimates, which run from June to June and include other adjustments.
