How this comparison is built

Both names are ranked by how many babies were registered with that exact spelling, so every position here counts real births rather than votes or searches. Rank is the only measure every source publishes, so it is what the charts plot; birth counts are not released for every place.

A place appears only in the years it published a complete list, which is why a name can be missing from a year it was almost certainly given to some babies. See every head-to-head on the site, or the ranked lists these names come from.
