Ranks and shares: girls’ names in each year’s SSA file; share of all girls SSA recorded that year.
Is Delta a boy’s or a girl’s name?
Of the 4,476 Americans recorded as Delta, 98% are girls and 2% boys. In 2025 it went to 78 girls; SSA lists no boys with it that year (fewer than 5, or none).
Years with fewer than 20 babies given the name are left blank.
Girls and boys named Delta: the SSA national file counts each sex separately.
How many people are named Delta, and how old are they?
2,550 alive in 2026, estimated
That is 57% of the 4,476 Americans ever recorded as Delta. The median Delta alive today is 35 years old; half are between 7 and 59.
The 2020 Census counted 2,483 people named Delta (2,308 women and girls, 175 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 2,219 born in the U.S. The Census count is 12% 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).
Where are babies named Delta born?
The states with the most babies named Delta are Mississippi, Florida and Indiana, with 71% of its births recorded by state in 2025; Mississippi and Indiana are not among the ten states with the most births.

Where Delta is more common than its national share predicts
Relative to its national share, Delta is most over-represented in Louisiana: since 1910 it was given 2.7 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 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 Delta 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 4,603 babies since 1880, Delta is the most given (97% of them). In 2025 it was given to 78 of their 78 babies (100%), 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.
Names that rose and fell in the same decades as Delta
Names whose births rose and fell across the same decades, measured on each decade’s share of births.
