Is Chieko a boy’s or a girl’s name?
Chieko has been recorded only for girls: SSA lists no boys with the name in 23 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Chieko: the SSA national file counts each sex separately.
How many people are named Chieko, and how old are they?
An estimated 19 Americans named Chieko and born in the U.S. are alive in 2026, too few to state an age range. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 1,044 people named Chieko (1,042 women and girls, 2 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 40 born in the U.S. The Census count is 26.1 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).

Where Chieko is more common than its national share predicts
Relative to its national share, Chieko is most over-represented in Hawaii: since 1913 it was given 155.8 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 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 Chieko with the births its national share predicts year by year, for states with at least 100 births of the name.
