Would be much more interesting to see absolute numbers compared instead.
My conjecture is that Mason is the biggest YoY decrease (11 -> 18), followed by Abigail and Michael (both 12 -> 17).
The counts elsewhere on the website show:
- Mason: 10,075 babies -> 9,040 babies (down 1,035)
- Abigail: 7,874 babies -> 6,938 babies (down 936)
- Michael: 9,783 babies -> 9,041 babies (down 742)
