Is Daysi a boy’s or a girl’s name?
Daysi has been recorded only for girls: SSA lists no boys with the name in 48 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Daysi: the SSA national file counts each sex separately.
How many people are named Daysi, and how old are they?
1,510 alive in 2026, estimated
That is 99% of the 1,535 Americans ever recorded as Daysi. The median Daysi alive today is 23 years old; half are between 15 and 31.
The 2020 Census counted 4,875 people named Daysi (4,859 women and girls, 16 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,373 born in the U.S. The Census count is 3.6 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 Daysi is more common than its national share predicts
Relative to its national share, Daysi is most over-represented in California: since 1970 it was given 2.4 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 Daysi with the births its national share predicts year by year, for states with at least 100 births of the name.
How common is the spelling Daysi?
Daysi is a less common spelling of Daisy: SSA has recorded 1,535 Daysi and 159,355 Daisy since 1880.
Of these 8 names spelled alike, given to 169,308 babies since 1880, Daysi is the third most given (<1% of them). In 2025 it was given to 33 of their 3,285 babies (1.0%), the second 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.
