How many people are named Billy, and how old are they?

190,000 alive in 2026, estimated

That is 49% of the 389,665 Americans ever recorded as Billy. The median Billy alive today is 63 years old; half are between 49 and 74.

The 2020 Census counted 173,433 people named Billy (2,014 women and girls, 171,419 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 225,135 born in the U.S. The Census count is 23% below that prediction. Possible reasons: people who give a short form or another name to the Census, and a survival estimate that can run high.

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 are babies named Billy born?

The states with the most babies named Billy are Texas, Tennessee and Oklahoma, with 30% of its births recorded by state since 1910; Tennessee and Oklahoma are not among the ten states with the most births.

States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among boys’ 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 Billy with the births its national share predicts year by year, for states with at least 100 births of the name.
