In this paper, we employ statistics of local governments (city, town, or village) in synthesizing individual households of a prefecture to reduce the error between synthesized statistics and actual statistics. Our previous method used estimated statistics of local governments with fewer than 200,000 people since those smaller local governments do not release their detailed statistics. To reduce the errors with prefectural statistics, we simultaneously employ statistics of smaller local governments in synthesizing population in a prefecture. Our experimental results show that we can make a 1/7 to 1/140 reduction in the error between synthesized statistics and actual statistics compared to the previous method.
