Billie by the numbers
In 2025, 331 babies in England and Wales were named Billie. In the US, 124 were, though that figure is from 2017, the most recent full year we hold.
For the size of the two countries, it is given far more often in England and Wales than in the US.
Its American peak was 3,241 babies in 1930, so it is a 1930s name that has since fallen a long way.
At its height, in 1930, about 1 in 360 American babies born that year was called Billie.
