Girls and boys named Chas: the SSA national file counts each sex separately.
How many people are named Chas, and how old are they?
1,240 alive in 2026, estimated
That is 39% of the 3,223 Americans ever recorded as Chas. The median Chas alive today is 37 years old; half are between 29 and 43.
The 2020 Census counted 1,628 people named Chas (136 women and girls, 1,492 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,287 born in the U.S. The Census count is 26% above that prediction. Possible reasons: the Census records the name people give, which for many is the short form Chas 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).
Names spelled alike
Of these 3 names spelled alike, given to 3,510 babies since 1880, Chas is the most given (92% of them).

Some are separate names, not spellings of one.
