Synthetic Method for Population of A Prefecture Using Statistics of Local Governments

In this paper, we employ statistics of local governments in synthesizing individual households of a prefecture in order to reduce the error between synthesized statistics and real statistics. In our previous method, we employed estimated statistics of local governments with population less than 200,000 people and separately synthesize populations of local governments in a prefecture. This causes a lot of differences between the synthesized population and the real statistics. In order to reduce the errors with prefectural statistics, we simultaneously employ the statistics of smaller local governments in synthesizing population of a prefecture. Our experimental results show that the proposed method can reduce 42% to 84% errors against the previous method.
