Girls and boys named Marly: the SSA national file counts each sex separately.
How many people are named Marly, and how old are they?
1,630 alive in 2026, estimated
That is 98% of the 1,665 Americans ever recorded as Marly. The median Marly alive today is 20 years old; half are between 13 and 31.
The 2020 Census counted 2,673 people named Marly (2,559 women and girls, 114 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,469 born in the U.S. The Census count is 1.8 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Marly rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.

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).

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 Marly with the births its national share predicts year by year, for states with at least 100 births of the name.
