Shading is the share of that state's recorded girls 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. Kirsty has too little recent state data to map, so this covers all years from 1910.
