    States with no published count are not listed with a number: SSA publishes a name only when at least 5 babies of one sex received it in that state in that year. Theodore may have been given to 1–4 boys in those states, but the count is not published and is never guessed here.

    Theodore ranks highest in Michigan: #1 in 2025, with 490 boys. The most Theodores were born in California: 1,211 boys in 2025, where it ranked #13.
