At 50 million articles and counting, Wikipedia is the largest source of human knowledge ever created—but it isn't complete. Wikipedia remains a work in progress, an ever-growing and evolving encyclopedia that provides free, reliable, and unbiased information to billions of people around the world.
Our 2018 annual report highlights the progress we made this past year. It reflects the achievements of the people and technology behind Wikipedia: the 250,000 volunteers each month who dedicate their time to expand Wikipedia’s knowledge base; the 350+ staff members who create the tools that keep Wikipedia running; and the generous donors who ensure that Wikipedia continues to be independent and ad-free.
Wherever you fit into the Wikimedia ecosystem, our accomplishments would not be possible without your participation. Thank you for your commitment to Wikipedia and free, open knowledge. Together, we’re making progress toward a world where everyone can freely share in the sum of all knowledge.
