Is Mar a boy’s or a girl’s name?
Of the 1,188 Americans recorded as Mar, 79% are girls and 21% boys. In 2025 it went to 120 girls and 9 boys.
Years with fewer than 20 babies given the name are left blank.
Girls and boys named Mar: the SSA national file counts each sex separately.
How many people are named Mar, and how old are they?
An estimated 957 Americans named Mar and born in the U.S. are alive in 2026 (81% of everyone recorded); the median is 13 years old and half are between 3 and 46. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 3,060 people named Mar (1,978 women and girls, 1,082 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 596 born in the U.S. The Census count is 5.1 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Mar 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).
Where are babies named Mar born?
The states with the most babies named Mar are California, Texas and Florida, with 90% of its births recorded by state in 2025.
| State | Births 2025 | Rank, girls | vs. national |
|---|---|---|---|
| California | 32 | #900 | 0.9× |
| Texas | 25 | #1,110 | 0.8× |
| Florida | 12 | #1,220 | 0.8× |
| Arizona | 8 | #792 | 0.4× |
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 Mar 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 2 names spelled alike, given to 2,168 babies since 1880, Mar is the most given (55% of them). In 2025 it was given to 129 of their 189 babies (68%), again the most given.
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.
