Local administrative regions
There are many relatively small regions based on local government agencies such as districts, agencies, or regions. In general, they are all regions in the general sense of being bounded spatial units. Examples include electoral districts such as Washington's 6th congressional district and Tennessee's 1st congressional district; school districts such as Granite School District and Los Angeles Unified School District; economic districts such as the Reedy Creek Improvement District; metropolitan areas such as the Seattle metropolitan area, and metropolitan districts such as the Metropolitan Water Reclamation District of Greater Chicago, the Las Vegas-Clark County Library District, the Metropolitan Police Service of Greater London, as well as other local districts like the York Rural Sanitary District, the Delaware River Port Authority, the Nassau County Soil and Water Conservation District, and C-TRAN (Washington), C-TRAN.
Traditional or informal regions
The traditional territorial divisions of some countries are also commonly rendered in English as "regions". These informal divisions do not form the basis of the modern administrative divisions of these countries, but still define and delimit local regional identity and sense of belonging. Examples are:
* England
* Regions of Finland, Finland
* Regions of Japan, Japan
* Regions of Korea, Korea
* Regions of Norway, Norway (''landsdeler'')
* Historical regions of Romania, Romania
* List of traditional regions of Slovakia, Slovakia
* List of regions of the United States, United States
Functional regions
Functional regions are usually understood to be the areas organised by the horizontal functional relations (flows, interactions) that are maximised within a region and minimised across its borders so that the principles of internal cohesiveness and external separation regarding spatial interactions are met (see, for instance, Farmer and Fotheringham, 2011; Klapka, Halas, 2016; Smart, 1974). A functional region is not an abstract spatial concept, but to a certain extent it can be regarded as a reflection of the spatial behaviour of individuals in a geographic space.
The functional region is conceived as a general concept while its inner structure, inner spatial flows, and interactions need not necessarily show any regular pattern, only selfcontainment. The concept of self-containment remains the only crucial defining characteristic of a functional region. Nodal regions, functional urban regions, daily urban systems, local labour-market areas (LLMAs), or travel-to-work areas (TTWAs) are considered to be special instances of a general functional region that need to fulfil some specific conditions regarding, for instance, the character of the region-organising interaction or the presence of urban cores, (Halas et al., 2015
).
Military regions
In military usage, a region is shorthand for the name of a military Military organization#Commands, formations, and units, formation larger than an Army group, Army Group and smaller than an Theater (warfare), Army Theater or simply Theater. The full name of the military formation is Army Region. The size of an Army Region can vary widely but is generally somewhere between about 1 million and 3 million soldiers. Two or more Army Regions could make up an Army Theater. An Army Region is typically commanded by a full General (US four stars), a Field Marshal, or General of the Army (US five stars), or Generalissimo (Soviet Union); and in the United States Armed Forces, US Armed Forces an Admiral (typically four stars) may also command a region. Due to the large size of this formation, its use is rarely employed. Some of the very few examples of an Army Region are each of the Eastern, Western, and southern (mostly in Italy) fronts in Europe during World War II. The military map unit symbol for this echelon of formation (see Military organization and APP-6A) is identified with six Xs.
Media geography
Media geography is a spatio-temporal understanding, brought through different gadgets of media, nowadays, media became inevitable at different proportions and everyone supposed to consumed at different gravity. The spatial attributes are studied with the help of media outputs in shape of images which are contested in nature and pattern as well where politics is inseparable. Media geography is giving spatial understanding of mediated image.
