Ranks: girls’ names and boys’ names ranked separately in each year’s SSA file; “under 5” is a year SSA did not list the name for that sex.
Is Ki a boy’s or a girl’s name?
Of the 535 Americans recorded as Ki, 20% are girls and 80% boys.
Years with fewer than 20 babies given the name are left blank.
Girls and boys named Ki: the SSA national file counts each sex separately.
How many people are named Ki, and how old are they?
An estimated 507 Americans named Ki and born in the U.S. are alive in 2026 (95% of everyone recorded); the median is 25 years old and half are between 16 and 37. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 3,725 people named Ki (1,386 women and girls, 2,339 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 486 born in the U.S. The Census count is 7.7 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.
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
Of these 8 names spelled alike, given to 13,061 babies since 1880, Ki is the fourth most given (4.1% of them). In 2025 none of their 263 babies recorded by SSA was a Ki (SSA lists a name only with 5 or more babies of one sex).
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 Ki
Names whose births rose and fell across the same decades, measured on each decade’s share of births.
Similar histories: each decade’s share of births, from the SSA national file, 1880-2025, published May 8, 2026. SSA’s notes on the data.
