Recorded 1880–2025 · United States
Missouri was most popular in 1889, when 40 American babies were given the name — ranking #636 that year. In 2025 it ranked #20,040, with 7 births. Across 1880–2025 the Social Security Administration has recorded 1,602 people named Missouri.
Across the whole record Missouri is a girl’s name — 100.0% of the 1,602 Americans given it were girls and 0.0% were boys. In births since 2016 it is 100% girls and 0% boys.
Counted from every US birth the Social Security Administration recorded under this name, so it reflects use rather than opinion. A name given to fewer than five babies of one sex in a year is withheld at source and is not counted.
