Is Winthrop a boy’s or a girl’s name?
Winthrop has been recorded only for boys: SSA lists no girls with the name in 82 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Winthrop: the SSA national file counts each sex separately.
How many people are named Winthrop, and how old are they?
An estimated 394 Americans named Winthrop and born in the U.S. are alive in 2026 (34% of everyone recorded); the median is 67 years old and half are between 56 and 76. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 560 people named Winthrop (4 women and girls, 556 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 466 born in the U.S. The Census count is 20% 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.
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 Winthrop is more common than its national share predicts
Relative to its national share, Winthrop is most over-represented in Massachusetts: since 1910 it was given 5.3 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 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 Winthrop with the births its national share predicts year by year, for states with at least 100 births of the name.
