The rank-size rule is a common standard by which urban primacy is established. A distribution such as that in the United States or China does not exhibit a pattern of primacy, but countries with a dominant "primate city" clearly vary from the rank-size rule in the opposite manner. Therefore, the rule helps to classify national (or regional ...

A primate city [1] is a city that is the largest in its country, province, state, or region, and disproportionately larger than any others in the urban hierarchy. [2]
Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.

The tests are the culmination of year-long Advanced Placement (AP) courses, which are typically offered at the high school level. AP exams (with few exceptions [1]) have a multiple-choice section and a free-response ...
The urban hierarchy ranks each city based on the size of population residing within the nationally defined statistical urban area. Because urban population depends on how governments define their metropolitan areas, urban hierarchies are conventionally ranked at the national level; however, the ranking can be extended globally to include all cities.
In different contexts, "scale" could have very different connotations, which could be classified as follows: [4] Geographic scale or the scale of observation: the spatial extent of a study. E.g. a spatial analysis of the entire United States might be considered a large-scale one, while a study on a city has a relatively small scale.
Map of human skin color distribution for native populations, by R. Biasutti in the von Luschan's chromatic scale for classifying skin color. It was reported that for areas with no data Biasutti simply filled in the map by extrapolation from findings obtained in other areas. [1] Skin colors according to von Luschan's chromatic scale
