How many people are named Joslin, and how old are they?
1,390 alive in 2026, estimated
That is 98% of the 1,416 Americans ever recorded as Joslin. The median Joslin alive today is 22 years old; half are between 15 and 33.
The 2020 Census counted 1,459 people named Joslin (1,361 women and girls, 98 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,329 born in the U.S. The Census count is 10% 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).
