Koby by the numbers
In 2025, 60 babies in England and Wales were named Koby. In the US, 96 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 American peak was 411 babies in 2000, so it is a 2000s name that has since fallen a long way.
