An estimated 782 Americans named Cyncere and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 10 years old and half are between 5 and 17. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 374 people named Cyncere (146 women and girls, 228 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 527 born in the U.S. The Census count is 29% below that prediction.
