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. Its US peak was 3,241 in 1930.
Looking further back: between 1880 and 2008, Billie was most common in 1930, when it went to 0.28% of American babies of that sex. Squarely vintage-revival territory.
