An estimate, not a count. SSA’s files count people born in the United States who received a Social Security number, so anyone born abroad is not in them; before 1937 most people got a number as adults, and their survival is counted from that age.
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 Dennise is more common than its national share predicts
Relative to its national share, Dennise is most over-represented in California: since 1935 it was given 2.1 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 Dennise with the births its national share predicts year by year, for states with at least 100 births of the name.
How common is the spelling Dennise?
Dennise is a less common spelling of Denise: SSA has recorded 3,571 Dennise and 374,789 Denise since 1880.
Of these 8 names spelled alike, given to 390,272 babies since 1880, Dennise is the third most given (<1% of them). In 2025 it was given to 7 of their 234 babies (3.0%), again the third most given.
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.
