Jack peaked in 1927, when 12,884 babies got the name.
At least 759,677 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.
Jack by decade
Among all names given to American babies, its best decade was the 2020s, when it ranked #23. The largest share of babies named Jack, 21.7%, were born between 1928 and 1945, the Silent Generation's birth years.
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 Jack is most common
Compared with all babies born in each state since 1910, Jack has been most common in Wyoming (2×), Montana (1.8×), and Oklahoma (1.7×), and least common in Hawaii (0.6×).
740,208 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.
