Thea peaked in 2018, when 1,209 babies got the name.
At least 20,118 babies have been given the name since 1880. Years SSA withheld, because fewer than 5 were born, are skipped rather than drawn as zero. * 2025 is the newest year published and it undercounts: a card application is filed some time after a birth.

Where Thea is most common
Compared with all babies born in each state since 1910, Thea has been most common in Utah (2.6×), Idaho (2.1×), and Minnesota (2.1×), and least common in Alabama (0.38×).
15,062 births recorded by state, 1910–2025. 2× means twice as common as nationally. States with fewer than 30 such births are left blank, and SSA withholds any year with fewer than 5 in a state, so small states read low.
