英文摘要	This paper examines the Zipfs law for the size distribution of Pakistani cities using the five census data from 1951 to 1998. We observe that Zipfs law does not hold in any of the five census years at national level. Next, we consider the city size distribution of four Pakistani provinces and find that Zipfs law is more likely to hold for cities at province-level. We attribute these findings to the coherence property of the urban system. In Pakistan the urban systems within provinces are more coherent in terms of common language, common culture and common rules as compared to the urban system as a whole at national-level.
