After four years working at the Wikimedia Foundation, the most frequent question I still get is how Wikipedia funding works, and whether it is true that the entire budget is covered with donations. Yes, this is true, and this graph shows the different sources. For the most part, these are unrestricted donations. Only a small percentage consists of restricted grants, given by other foundations for specific purposes of Wikimedia research and development. Knowing that my salary comes from donations of many individuals makes me very conscious about where to put my time and attention (and where not)!
