Frequently asked questions

What is the most popular baby name in Delaware?
For births registered in 2025, Noah was the top boy's name (63) and Mia was the top girl's name (43), according to Social Security card applications filed for Delaware births.
Where does this Delaware data come from?
The Social Security Administration publishes a state-specific file of names taken from Social Security card applications. It covers 2008 onward in the range shown here and is public domain.
Why are some names missing from the Delaware list?
SSA withholds any name with fewer than 5 occurrences in a state and year. That is a privacy rule, not a gap in the records, so a missing name means "fewer than 5", never zero.
Do these counts include every baby born in Delaware?
They include births with a Social Security card application that lists Delaware as the state of birth. Names are counted as written on the application, so spelling variants are counted separately.
How often is the Delaware ranking updated?
SSA releases the previous year's data annually, usually in the first half of the following year. Past years do not change once published.
