Geography and World Regions: Content Summary G.2: Regionalization

Regions are areas created to cohesively organize space based on the presence or absence of human or physical characteristics. (G.2.A)

In contrast, places are specific areas that have certain physical and human characteristics and significance. (G.2.A)

Geographers combine places with common physical or human characteristics into regions to aid analysis and to present a complex earth in simpler terms. (G.2.A)

Physical characteristics such as climate, networks of waterways, land topography, soil types, and vegetation may all play a role in defining a region. (G.2.A)

Geographers categorize regions as formal (uniform), functional (nodal), and perceptual (vernacular). (G.2.B)

Because humans define regions in an attempt to categorize and organize geographic space, regions naturally reflect the beliefs, perceptions, and attitudes of humans, either within or outside the region. (G.2.B)

Functional (nodal) regions are focused on a node or central point that influences or connects an area and radiates out from the center—for example, a newspaper distribution territory or centralized retail or medical services. (G.2.B)

Perceptual (vernacular) regions are defined by the beliefs, perceptions, and attitudes people have about a particular area. They are informal and may be tied to the “impressions” one has of an area. (G.2.B)

Perceptual (vernacular) regions are defined by the beliefs, perceptions, and attitudes people have about a particular area. They are informal and may be tied to the “impressions” one has of an area. (G.2.B)

Regions often represent generalizations about a place and may not reflect the full complexity and diversity present within the region. (G.2.B)

Geographic scale allows for the study of characteristics from a very localized region to expansive and broad characteristics on global levels. (G.2.C)

Geographic scale allows for the study of characteristics from a very localized region to expansive and broad characteristics on global levels. (G.2.C)

Geographers may also employ very general criteria to define a large, global region, such as “sub-Saharan” Africa or the “Global North” and “Global South.” (G.2.C)

Places within these regions may or may not fully embody the established characteristics for the regions, or there may be overlap between regions. (G.2.C)

Geographers continually debate and revise the borders and structures of regions to establish coherent generalizations about space. (G.2.D)

If a region is defined by rainfall, animal habitat, or agricultural use, the space attributed to that region may need to be adjusted if climate patterns or land uses change. (G.2.D)

Population growth and decline on local and regional levels may change the ways in which people are divided for the purposes of political representation or provision of cultural, government, and economic services. (G.2.D)

Migration into and out of a region may lead to changes in cultural characteristics, such as predominant language, prevailing religions, and types of food, either in places within the region or throughout the region as a whole. (G.2.D)
