Millie by the numbers

In 2025, 1,080 babies in England and Wales were named Millie. In the US, 885 were, though that figure is from 2017, the most recent full year we hold.

For the size of the two countries, it is given several times more often in England and Wales than in the US.

Its best year in America so far is the most recent one on record, which means it was still climbing when the records end.

At its height, in 1880, about 1 in 930 American girls born that year was called Millie.
