This page in a nutshell: Everyone – including you – can make improvements to Wikipedia, the free encyclopedia.

You do. Yes, anyone can be bold and edit an existing article or create a new one, and volunteers do not need to have any formal training. The people who create and edit articles on Wikipedia come from many countries, with individuals who all bring something different with them, but most importantly a willingness to help in building a free encyclopedia of reliable information. Any contributor to this encyclopedia, unregistered and registered alike, is called a "Wikipedian", or, more formally, an "editor" of the encyclopedia. Almost all Wikipedians are volunteers. Other categories of Wikipedians have emerged as well.

The English Wikipedia currently has 48,218,692 users who have registered a username. In the last year, less than a million registered editors made any edit, and most of those have only made a few edits ever.

Only a minority of users contribute regularly (120,074 have edited at all in the last 30 days; less than 10% of them averaged at least one edit per day) Only a minority of those contributors participate in community discussions.

An unknown but relatively large number of unregistered Wikipedians also contribute to the site.

The type of people who were drawn to writing an encyclopedia for fun tend to be pretty smart people.

Nationality

The greatest number, or plurality, of editors (20%) reside in the United States, followed by Germany (12%) and Russia (7%). The only country not in Europe or North America in the top 10 is India (3%).

Contributions come from diverse demographic and ethnographic segments:

• Mid-20s males and retired males are the largest demographics. See Gender database reports.
• 10–20% women of various ages, significant underrepresentation acknowledged by Gender bias on Wikipedia and Gender gap
• Students (e.g., in the context of a course)
• Enthusiasts (e.g., people with interest in a particular subject, like butterflies)
• Insiders (e.g., people who work for an organization, such as the Sierra Club)
• Dabblers (e.g., people who see some problem with an article and want to help)
• Scholars (e.g., researchers who want to use Wikipedia as an additional dissemination platform)
• Archivists (e.g., people who work or volunteer at a museum, archive, or library wanting to contribute artifacts, like 18th-century paintings)
• Marketers (e.g., individuals, staff, members, or a PR firm seeking to promote a product, service, or brand)
• Evil-doers (e.g., spammers, vandals)

Many people in the Wikipedia community are conscious that the demographics of editors has systemic bias in the content of the site and efforts are being made to remedy these biases.

The content of any particular article is subject to editorial discretion developed via consensus. Wikipedia is not paper, which means we can write almost an unlimited amount on any topic. Still, there are limits on what we ought to include, and especially how we ought to write it. When an article is incomplete or inaccurate, you can edit the article to be more accurate and/or useful. Someone may place a notice at the top of the article indicating that it needs to be cleaned up. It is also possible to create a new article to share information that is not yet in Wikipedia.

The way to decide whether a particular statement is accurate is to find independent reliable sources to affirm that statement, such as books, magazine articles, television news stories, trade journals, or other websites. For more guidance on evaluating the accuracy of Wikipedia articles, see researching with Wikipedia. It is Wikipedia's policy to add to the encyclopedia only statements that are verifiable and not original research. The Wikipedia style guide encourages editors to cite sources. Detailed citations allow readers of the article to easily verify the content in question.

When a large group of people work to compile information on a given topic, disputes may arise. A useful feature of Wikipedia is the ability to tag an article, or a section of the article, as subject of a dispute about a neutral point of view. This feature is especially popular for controversial topics, topics subject to changing current events or other topics where divergent opinions exist. To resolve the dispute, the interested editors will share their points of view on the article's talk page. They will attempt to reach consensus so that all valid perspectives can be fairly represented. This allows Wikipedia to be a place not only of information, but of collaboration. Many users of Wikipedia consult the page history of an article in order to assess the number, and the perspective, of people who contributed to the article. You may also consult the talk page of any article to see what other readers and editors have to say about it.

Wikipedia's best articles are highlighted in the list of featured articles. These articles were granted "featured" status because they were judged to be of high quality by other editors and users. (If later edits reduce the quality of a featured article, a user can nominate an article for removal from the list.)
