Despite different methods of ranking cities, the largest and most economically powerful cities tend to be dominant in the urban hierarchy. These cities often have large populations, extensive infrastructure, and are centers for business, culture, and politics. Examples of such cities include New York, Tokyo, London, Paris, and Beijing.
In terms of regions with high numbers of cities in higher rankings of the urban hierarchy, it depends on the specific ranking system used. However, in general, regions with high levels of economic development and urbanization tend to have a larger number of cities in higher rankings. For example, North America, Europe, and Asia have many of the world's largest and most economically powerful cities. Within these regions, certain countries such as the United States, China, Japan, Germany, and the UK tend to have higher numbers of cities in higher rankings of the urban hierarchy. However, it is worth noting that there are also some cities in less developed regions that rank highly in certain ranking systems, such as Dubai in the United Arab Emirates or Sao Paulo in Brazil.
