Is Isobel a boy’s or a girl’s name?

Isobel has been recorded only for girls: SSA lists no boys with the name in 103 years of records (it lists a name only in years with 5 or more babies of a sex).

Girls and boys named Isobel: the SSA national file counts each sex separately.

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

2,620 alive in 2026, estimated

That is 69% of the 3,802 Americans ever recorded as Isobel. The median Isobel alive today is 15 years old; half are between 8 and 23.

The 2020 Census counted 2,764 people named Isobel (2,754 women and girls, 10 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 2,220 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.

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 Isobel is more common than its national share predicts

Relative to its national share, Isobel is most over-represented in New York: since 1910 it was given 1.1 times as often there as its national share each year would predict.

New York1.09×

Bars start at 1× (as often as the national share predicts).

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