Cynthia peaked in 1957, when 39,416 babies got the name.
At least 713,412 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.

Among all names given to American babies, its best decade was the 1950s, when it ranked #26. The largest share of babies named Cynthia, 59.4%, were born during the baby boom (1946–1964).
Rank counts both sexes together, among every name SSA recorded that decade; the number under it is births. The 2020s run only to 2025. Generation years follow Pew Research Center, which has not named a generation after 2012.
Where Cynthia is most common
Compared with all babies born in each state since 1910, Cynthia has been most common in District of Columbia (1.5×), Connecticut (1.2×), and Alaska (1.2×), and least common in Utah (0.47×).
707,618 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.
