Names unique to Delaware

The most distinctive Delaware baby names, 1910–2025

These are the names given far more often in Delaware than anywhere else in the country, across the whole record from 1910 to 2025. Kasai leads: it is given about 8× more often here than across the United States as a whole.

The multiplier compares each name's share of Delaware births with its share nationally, and reports the conservative low end of that comparison — so a name carried by a handful of births cannot outrank one carried by hundreds.

Across the whole record, 1910–2025

Right now, in 2025

A different list from the one above, and not a contradiction: these are the names distinctive to Delaware in a single recent year rather than across the whole record.
