How many people are named Deniss, and how old are they?
An estimated 86 Americans named Deniss 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 351 people named Deniss (247 women and girls, 104 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 86 born in the U.S. The Census count is 4.1 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Deniss rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.
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).
