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).
Names spelled alike
Of these 8 names spelled alike, given to 387,939 babies since 1880, Jonni is the eighth most given (<1% of them). In 2025 none of their 1,295 babies recorded by SSA was a Jonni (SSA lists a name only with 5 or more babies of one sex).
