It's Pretty Much The Same Throughout The Country, With A Couple Of Notable Exceptions

As Ancestry.com explains, you'll have to travel to the Southwest portion of the country for some surname variety:

Only the Southwestern portion of the country really has a lot of variety. States like Texas, California, New Mexico, and Arizona — where there are large Latino populations — boast a variety of names like Garcia, Hernandez, Martinez, and Chavez. And then there’s Hawaii, whose three most-common surnames — Lee, Wong and Kim — don’t even appear in the top three anywhere else in the country.

Massachusetts, having a large population of those with Irish ancestry, is the only state in the nation where the surname Sullivan is in the top three.
