Sources of Surname Data
We are primarily interested in sources of surname data that contain both surnames and countries of birth for surnames.
Internet Movie Database (IMDB)
The Olympic Athletes data was taken from the relevant pages on wikipedia. Local copies of all of the individual country pages from the 2004 Summer Games were retrieved by script (Olympics-RetrievePageURLs.pl) that used an offline version (Olympics-OfflineSource.html) of the wikipedia Nations at the 2004 Summer Olympics page. This script also constructs a list of countries participating (http://www.edegan.com/repository/Olympics-ParticipatingCountries.txt Olympics-ParticipatingCountries.txt]).
