How many people are named Merrilyn, and how old are they?
An estimated 382 Americans named Merrilyn and born in the U.S. are alive in 2026 (51% of everyone recorded); the median is 77 years old and half are between 70 and 82. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 592 people named Merrilyn (592 women and girls, 0 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 474 born in the U.S. The Census count is 25% 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).
