“City sizes follow a power law distribution (Zipf's law), where the largest city is roughly twice the size of the second largest, three times the third, and so on -- an example of Extremistan dynamics.”

A meta-analysis of 29 published studies found that the combined estimate of Pareto exponent is significantly greater than one, suggesting a more even city size distribution than pure Zipf's law predicts.

Power laws appear to describe the distributions of city sizes, firm sizes, income, and wealth reasonably well, at least in the upper tail.

The standard Zipf analysis misses substructure in city size distributions. Pure power law fits are rejected for many countries when proper statistical tests are applied.
