Is Demetrio a boy’s or a girl’s name?
Demetrio has been recorded only for boys: SSA lists no girls with the name in 116 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Demetrio: the SSA national file counts each sex separately.
How many people are named Demetrio, and how old are they?
2,330 alive in 2026, estimated
That is 76% of the 3,064 Americans ever recorded as Demetrio. The median Demetrio alive today is 33 years old; half are between 21 and 52.
The 2020 Census counted 5,064 people named Demetrio (18 women and girls, 5,046 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 2,325 born in the U.S. The Census count is 2.2 times 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 Demetrio is more common than its national share predicts
Relative to its national share, Demetrio is most over-represented in Texas: since 1910 it was given 3.8 times as often there as its national share each year would predict.
States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among boys’ 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 Demetrio with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
Of these 6 names spelled alike, given to 10,604 babies since 1880, Demetrio is the second most given (29% of them). In 2025 it was given to 17 of their 103 babies (17%), the third most given that year.
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 and in 2025, and each name’s peak year, from the SSA national file, published May 8, 2026. Some are separate names, not spellings of one.
