Manual:Article

An article has a couple of definitions in MediaWiki terms, owing to different opinions about what an article is; some maintain that an article is a page in the article namespace, which is a fair assertion. However, MediaWiki uses a specific definition of an "article" when determining whether or not to include a page in the "content pages" statistic on Special:Statistics.

In MediaWiki terms, an article is a page in the main namespace, or a content namespace (see $wgContentNamespaces) that is not a redirect and contains at least one internal link. When there is embedded an image this counts also as an internal link.
