Mark Graham mapped “the percentage of local edits to [Wikipedia] articles about places” in order to measure “the percentage of edits about any country that come from people with strong associations to that country”:
Unsurprisingly, they show that in predominantly English-speaking countries most edits tend to be local. That is, we see that most Wikipedia articles (85%) about the US tend to be written from America, and most articles about the UK are likewise written from the UK (78%). The Philippines (68%) and India (65%) score well in this regard, likely because of role that English plays as an official language in both countries. But why then do we see relatively low numbers is other countries that also have English as an official language, such as Nigeria (16%) or Kenya (9%)?
His takeaway:
Some parts of the world are represented on one of the world’s most-used websites predominantly by local people, while others are almost exclusively created by foreigners, something to bear in mind next time you read a Wikipedia article.
