Wikipedia:Categories/Special categories
From the Simple English Wikipedia, the free encyclopedia that anyone can change
Certain category groups have special uses or requirements.

[change] Geographic based categories
Categories that are based on geography and nationality (for example, Category:Towns in Germany, Category:Buildings and structures in London and Category:Chinese people) all use the same basic structure. Nationality categories are sub-categories of their associated geography categories (Category:English people is a sub-category of Category:England) as well as what ever other categories apply (Category:English people is also a people based category so it is a sub-category of Category:British people
The top level of each category is based on the continent it is a part of. The next level would be Country. Each country is seperatd into the major sub-division of that country (states, regions and provinces) and then smaller subdivisions (counties). This is repeated down until the municipality level (city, town) is reached.
Categories are only seperated down to the point there is enough articles to need it. The municipality level is usually only needed for the largest of cities. In some cases, steps between categories can be skipped. For example, in most countries, the city category is a part of the country category because there is not enough need for the steps in between.
[change] Country subdivisions
A sample of commonly seen country sub-divisions is seen below.
| United States | Germany | England | Switzerland | Canada |
|---|---|---|---|---|
| State | State | Region | Canton | Province |
| County | Government region | County | District | County |
| Municipality | District | Municipality | Municipality | Municipality |

[change] Examples
- Raleigh is a city in the American state of North Carolina. The city is in Wake County. The category set-up for it is Category:Wake County, North Carolina (it's county) -> Category:North Carolina counties (in Category:North Carolina, it's state) -> Category:Counties in the United States (in Category:United States, it's country) -> Category:North America (it's continent}}. Category:Raleigh, North Carolina (the city itself}} does not exist because there is currently no need for it. If it did exist, it would be a sub-category of the county category (Wake County, North Carolina).
- Big Ben is a clock tower in London. Its category set-up is Category:Buildings and structures in London -> Category:Buildings and structures in England -> Category:Buildings and structures in the United Kingdom -> Category:Buildings and structures in Europe.
[change] The United Kingdom
The United Kingdom is a special case. It includes the countries of England, Scotland, Wales and Northern Ireland as well as many other areas. Many of these areas do not have their own categories. Another problem is that if something is termed "British" (from the United Kingdom), it may not be possible to know if it is actually one of the countries which make up the United Kingdom. If the actual country is known, it should be used. If it is not known, the British/United Kingdom level should be used.
[change] Musical entertainers
The Category:Musical entertainers is used to group all entertainers who deal with music.
[change] Main level
The main category includes sub-categories for singers, songwriters, musicians, bands, composers and conductors. The category is broken down into each of these major groups as well as Category:Musical entertainers by nationality.
[change] Secondary levels
The secondary levels (the sub-categories) are mainly broken down into a combination of nationality and occupation. Examples of this are Category:English singers and Category:German musicians. The categories use the same basic set-up for nationality as the Geography categories.
