Chan

A sex is only published in years it reached five applications, so a stretch at 0% or 100% means the other side stayed under that floor — not that it was never used.

Deeper origin not confirmed in the cited records

Grouped by closeness of spelling (up to two letter changes), same sex, with a floor on all-time use. It catches Sophia/Sofia and Aiden/Ayden, and misses spellings that sound alike but look different, like Sean and Shawn.

Shading is the share of that state's recorded boys given this name, not the raw count — otherwise the map would just show which states are biggest. Unshaded states have no published records for this period. U.S. birth records suppress state-year counts below 5; state counts therefore don't add up to the national total. Every state links to its full rankings. Chan has too little recent state data to map, so this covers all years from 1910.
