How many people are named Rook, and how old are they?
An estimated 744 Americans named Rook and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 7 years old and half are between 3 and 12. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 464 people named Rook (69 women and girls, 395 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 388 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).
