Changes

A list of all actors and their birth countries was extracted from the [http://www.imdb.com/interfaces#plain IMDB biographies file] using a simple one-off script ([http://www.edegan.com/repository/IMDB-ExtractNamesAndCountries.pl IMDB-ExtractNamesAndCountries.pl]). This produced the input file http://www.edegan.com/repository/IMDB-BioData.txt IMDB-BioData.txt]. Much as with the Olympics data the country names were then corrected to the [[UN GeoRegion standard name| UN GeoRegions]], with individuals who were born in non-recognized jurisdictions, such as on a cruise ship at sea, excluded (see [http://www.edegan.com/repository/IMDB-BiosUNCountryCodes.txt IMDB-BiosUNCountryCodes.txt]).
