How many people are named Jupiter, and how old are they?
1,740 alive in 2026, estimated
That is 99% of the 1,749 Americans ever recorded as Jupiter. The median Jupiter alive today is 5 years old; half are between 3 and 8.
The 2020 Census counted 818 people named Jupiter (403 women and girls, 415 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 728 born in the U.S. The Census count is 12% above that prediction. Possible reasons: the Census counts people born abroad, whom SSA’s files leave out, and it records the name people give, which SSA may have recorded under another spelling or as part of a compound name.
Alive today, by age
Alive today, by generation
| Generation | Born | Alive |
|---|---|---|

| Generation Alpha | 2013-2025 | 1,670 |
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).

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 Jupiter with the births its national share predicts year by year, for states with at least 100 births of the name.
