| Research Abstract |
Human population is one of the fundamental data in public administration. The change in the human population in a given region depends on the natural increase of population and the population migration due to the political and economic situation. In this work, we have shown the characteristic change in the municipal population distribution using the census data of Japan. Especially, we have shown that the great merger of municipalities might cause the violation of Zipf's law which is globally observed in the city size distribution. In addition, we constructed the model of population migration to have confirmed that the great merger of municipalities violates Zipf's law.
