The book Scale: The universal laws of life and death in organisms, cities and companies, by Geoffrey West, from the Santa Fe Institute, which I discussed in the previous post, asserts that cities and companies are subject to laws very similar to those that apply to living beings. They are general laws, applicable to all entities of these types, regardless of their origin. West explains it this way:
Remarkably, analyses of such data show that, as a function of population size, city infrastructure—such as the length of roads, electrical cables, water pipes, and the number of gas stations—scales in the same way whether in the United States, China, Japan, Europe, or Latin America. As in biology, these quantities scale sublinearly with size, indicating a systematic economy of scale but with an exponent of about 0.85 rather than 0.75...[F]ewer roads and electrical cables are needed per capita the bigger the city. Like organisms, cities are indeed approximately scaled versions of one another, despite their different histories, geographies, and cultures, at least as far as their physical infrastructure is concerned.
