Is Jos a boy’s or a girl’s name?
Jos has been recorded only for boys: SSA lists no girls with the name in 15 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Jos: the SSA national file counts each sex separately.
How many people are named Jos, and how old are they?
An estimated 81 Americans named Jos and born in the U.S. are alive in 2026, too few to state an age range. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 779 people named Jos (89 women and girls, 690 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 75 born in the U.S. The Census count is 10.4 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Jos rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.
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
Spelled alike: names in the SSA national file with the same pattern of letters and sounds and at most two letters apart, and Wiktionary’s listed forms; births since 1880. Some are separate names, not spellings of one.
