Technical notes:

• assumes these classes are disjoint (actually not), and that a single item does not belong to two or more of them. Therefore, the relative sizes of classes are somewhat accurate, but the number of items with other P31/P279 is lower then the correct number.
• items considered = items with sitelink - instances of category - instances of templates - instances of modules.
• other possible classes: organization (Q43229) may be interesting but may overelap architectural structure (for instance, a museum is often marked as both). geographic location (Q2221906) needs review as it currently includes music album.
• the number of items in class artificial object (Q16686448) are excluding items in other classes. This includes human settlements, albums, singles, books, paintings, scientific journals, songs, video games, television programs, etc.
• the number of items in class architectural structure (Q811979) are excluding items in class administrative territorial entity (Q56061). As of 2015-07-18 there're 919,394 items in both classes, most of which are villages.
