Wikipedia: A quantitative analysis (doctoral thesis summary)
The Gini coefficient (as well as other well-known inequality metrics) shows that less than 10% of the total number of logged editors in each language version is performing more than 90% of the total number of edits.
Quantitative analysis of logged-in authors in the ten largest Wikipedia language editions. Per-author edit counts follow Pareto-like distributions; the inequality analysis reports that less than 10% of logged editors per language version make more than 90% of edits, with monthly Gini coefficients of 80 to 85% since 2004. The companion HICSS 2008 paper (Ortega, Gonzalez-Barahona and Robles, doi 10.1109/HICSS.2008.333) was not read. Logged-in authors only; anonymous edits and bots are outside the analysis.
