Rank-Size Rule... Valid or Invalid?
The rank-size rule is both valid and invalid within China. There are certain cities that show a close proximity to the estimated population, but there are those who stray far from it. Both Peking, and Tianjin have close populations to their estimated populations, while Xian, and Chongqing are somewhat far away for theirs. Yes, any model will never be perfect, because of the different structures of the different countries, but overall I think that this is a good model that model that represents China. The rank-size rule is more valid than invalid, in my opinion.
