Casey by the numbers

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

Its American peak was 4,131 babies in 1990, so it is a 1990s name that has since fallen a long way.

At its height, in 1990, about 1 in 520 American babies born that year was called Casey.
