I have a sheet I photocopied from a book once, listing the top 20 surnames in telephone books in six different cities.  (I think the list is from the 1970's, but I'm not sure.)  Talk about reinforcing stereotypes.

• Boston's list included Sullivan, Murphy, McCarthy, O'Brien, Kelly, MacDonald, and O'Connor.
• New York's included Cohen, Schwartz, Levine, Friedman, Goldstein, Levy, and Goldberg.
• Milwaukee's included Schmidt, Mueller, Schultz, Krueger, Meyer, Schneider, Schroeder, and Fischer.
• San Francisco's included Lee and Wong.

But the winner was definitely Minneapolis.  The top ten names in order were Johnson, Anderson, Nelson, Peterson, Olson, Larson, Carlson, Smith, Miller, and Thompson.

It sounds about right. I lived in a house that got the Minneapolis phone book in the 70's. I would add that the list probably doesn't count the many alternate spellings from other Scandinavian areas, like Andersson and Andersen.
