Context A census **of** all the wikis hosted in [Wikia][1] (Now renamed to Fandom). A dataset consisting on data of more than 300 thousand wikis, such as: language, topic, number of users, admins, articles, edits, pages, number of users with a certain number of contributions, number of bots, etc. A study of this data has been presented in the [Opensym 2018 conference][2]. You can find the Jupyter notebook code regarding that study under the "Kernels" section. Content There are several files of data: - wikia_stats.csv: general data about each wiki. - wikia_stats_users.csv: general data about each wiki + number of human registered users, categorized according to the number of edits in the last 30 days (Users_N). - wikia_stats_users_birthdate.csv: all the data above plus the estimated date of birth. **If you are just looking for the whole dataset corresponding the Wikia census, go for the `wikia_stats_users_birthdate.csv` file** The other two .txt files contains pairs of (name, url) of the raw index crawled from the Wikia Sitemap, and the corresponding curated index with only the working wikis. The date of the data collection of this second version is October 2018. First version was February 2018. The collection of the data has been made using the scripts located here: https://github.com/Grasia/wiki-scripts The license of the data is not clearly stated by Wikia, because this data is publicly available in their website but they haven't established anything in their [license policy][3].
