Where this data comes from
Figures from 1996 onwards are the Office for National Statistics' annual baby-name registrations for England and Wales, which record every name given to three or more babies in a year. Figures before 1996 are estimates: the ONS published only top-100 rankings at ten-year intervals back to 1904, so counts for those years are modelled from the rankings, calibrated against Douglas Galbi's long-run research into English name frequencies, and shown with an uncertainty band. Estimates of living bearers combine these birth figures with national life tables and ONS mid-year population estimates.
One limit worth naming: these figures count names as registered at birth. Anyone who changes their name later in life - including trans people, and anyone who adopts a different name by deed poll or simply by use - is not reflected here. Birth registrations record where a name began, not the name a person lives with.
