Decade-by-Decade Leaders
The #1 boy and girl name in Idaho for each decade
How we calculated this
For each decade, we sum every year's SSA state-level birth count per name, then take the single name with the highest ten-year total for each sex. A name can lead a decade with a strong single peak year or with steady, moderate demand across all ten years, the total treats both the same way.
