The most common names of people born in Montana

Social Security has recorded about 1 million births in Montana since 1910 under names it lists. By our estimate, about 680,000 of those people are alive today, and their average age is 46. The most common names among them are Mary for women and Michael for men.

These are the names of people born in Montana, wherever they live now. Social Security records state of birth, not where people live, so people who moved to Montana from elsewhere aren't counted here, and people born here who moved away are.

About these numbers

Social Security publishes names by state of birth for births from 1910 on, listing a name only when at least five babies of the same sex got it in the state that year, so rare names are missing. We estimate how many of those babies are alive with SSA's national cohort life tables (there are no state tables), and count a name as a girls' or boys' name by which sex has more living people born here. “Vs. national” compares the name's share of living people born in Montana with its share of all living Americans in the national records. How we calculate this
