27,600 alive in 2026, estimated
That is 99% of the 27,777 Americans ever recorded as Londyn. The median Londyn alive today is 10 years old; half are between 6 and 14.
The 2020 Census counted 15,826 people named Londyn (15,477 women and girls, 349 men and boys).

Alive today, by age
Alive today, by generation
| Generation | Born | Alive |
|---|---|---|
| Millennials | 1981-1996 | 105 |

| Generation Alpha | 2013-2025 | 20,500 |
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 Londyn is more common than its national share predicts
Relative to its national share, Londyn is most over-represented in Mississippi: since 1989 it was given 3.1 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 Londyn with the births its national share predicts year by year, for states with at least 100 births of the name.
