Gender-neutral names typically start out masculine and become more female over time, but in recent years some names like Rowan have actually become more popular with boys. The interactive version allows you to customize the gender balance range, year range, and display (orientation/sort order).

Interesting. In the UK I feel like Rowan has always traditionally been a boy’s name.
I always shared this kind of interesting information with my students….😬
Angel is a bit misleading; it is most likely nearly 100% a girl’s name among non-Hispanics and mostly if not entirely a boy’s name among Hispanics.
