How many people are named Zi, and how old are they?
An estimated 131 Americans named Zi and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 20 years old and half are between 13 and 21. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 1,324 people named Zi (568 women and girls, 756 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 130 born in the U.S. The Census count is 10.2 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 8,444 babies since 1880, Zi is the sixth most given (1.6% of them). In 2025 none of their 428 babies recorded by SSA was a Zi (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.
