On 2006-01-07 I sampled 100 random articles to find that on Wikipedia:
- Articles meeting good article criteria make up 0% of articles.
- Articles over four paragraphs long but not good articles make up 28% of articles.
- Articles less than four pargraphs but not stubs make up 14% of articles.
- Stubs over three sentences long or including infoboxes or lists make up 27% of articles.
- Substubs less than three sentences long or not establising context make up 14% of articles.
Of the remaining articles:
- 8% are lists.
- 3% need wikifying or cleanup.
- 5% are disambiguation pages.
- 1% need to be merged and redirected.
- 0% are listed for deletion.
Additionally, of the above categorised articles:
- 1% start with the wording "Topic is the name of..." and then turn out to be an article about the topic and not the name.
- 2% use a new paragraph for every sentence.
- 1% are about schools.
- 8% are about settlements.
- 4% were made by Rambot (but may have been expanded since).
- 3% use redundant headings like "Biography" and "Details".
- 2% have three or more references.
- 1% were started by me.
