The thing is, what you need is relative importance of nearby cities. Nearby
cities are not so much subject to cultural background bias, because they
are usually from similar cultures.

Here's a list of some cities and wikipedias (number of wikipedia articles
in different languages about a city). I think it looks pretty good.

New York - 192 (more than nearby Washington even though Washington is
capital)
Tokyo - 192
São Paulo - 188 (more than nearby Rio de Janeiro)
Washington - 182
Wien - 176 (more than nearby Bratislava)
Rio de Janeiro - 156
Bratislava - 153
Baghdad - 152
Zagreb - 142 (more than nearby Ljubljana)
Mecca - 138 (more than nearby Jeddah, even though it has less then half the
population)
Ljubljana - 130
Montevideo - 125
Ulan Bator - 121
Bamako - 113
Jeddah - 106
Perth - 95
Casablanca - 93
