An estimate, not a count. SSA’s files count people born in the United States who received a Social Security number, so anyone born abroad is not in them; before 1937 most people got a number as adults, and their survival is counted from that age.
Living estimate: SSA births carried forward with the survival rates in SSA’s cohort life tables (2024 Trustees Report) for each birth year and sex. How the estimate is made. Count: Census Bureau, first names in the 2020 Census (released April 14, 2026; names reported 100 or more times, with the Bureau’s disclosure-avoidance adjustment).

Where Jill is more common than its national share predicts
Relative to its national share, Jill is most over-represented in Iowa: since 1910 it was given 1.9 times as often there as its national share each year would predict.
States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among girls’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Jill with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
Of these 4 names spelled alike, given to 209,611 babies since 1880, Jill is the most given (100% of them). In 2025 it was given to 21 of their 21 babies (100%), again the most given.

Some are separate names, not spellings of one.
