Initially only available in English, editions in other languages were quickly developed. Wikipedia's editions, when combined, comprise more than 62 million articles, attracting around 2 billion unique device visits per month and more than 14 million edits per month (about 5.2 edits per second on average) as of November 2023.[8][W 1] 26% of Wikipedia's traffic is from the United States, followed by Japan at 5.9%, the United Kingdom at 5.4%, Germany at 5%, Russia at 4.8%, and the remaining 54% split among other countries, according to data provided by Similarweb.[9]

Wikipedia has been praised for its enablement of the democratization of knowledge, extent of coverage, unique structure, and culture. It has been criticized for exhibiting systemic bias, particularly gender bias against women and geographical bias against the Global South (Eurocentrism).[10][11] While the reliability of Wikipedia was frequently criticized in the 2000s, it has improved over time, receiving greater praise in the late 2010s and early 2020s,[3][10][12][note 4] having become an important fact-checking site.[13][14]

Wikipedia has been censored by some national governments, ranging from specific pages to the entire site.[15][16] Articles on breaking news are often accessed as sources for frequently updated information about those events
