Workplace Assignment to Workers in Synthetic Populations in Japan
Tadahiko Murata, Daiki Iwase, Takuya Harada

In this paper, we assign a workplace to each worker in synthetic populations. We employ National Census and Economic Census released by Japanese Government. Using ODI (Origin-Destination-Industry) data in the statistics of the National Census, we assign workplace. We show the difference of workplace assignment when the ODI data is not available.

Evaluation of Synthetic Population Synthesized Using the Statistics of a Virtual City
Takuya Harada, Tadahiko Murata, Shingo Takahashi

In this paper, we evaluate the structures of households synthesized from the statistics of a virtual city. Since it is difficult to evaluate the synthetic population with the household compositions in the real population, we employ statistics that are calculated from a virtual city and we compare the household compositions with those of the virtual city. We found that our latest synthetic method has the least error with the household compositions in the virtual city.

Synthetic Individual Households by Prefecture Considering Statistics of Local Governments

In this paper, we propose a method to synthesize populations of cities, towns, and villages in the same prefecture simultaneously. Our previous method synthesize population by each city by dividing the statistics of the prefecture by the size of the population of the city. Therefore every city has the same statistical tendencies of the prefecture in the previous method. In the proposed method, the sum of statistics from each city, town and village is adjusted to the prefectural statistics to keep each statistical characteristics.

Income Allocation to Workers in Synthetic Populations Using Basic Survey on Wage Structure
　Sho Sugiura, Tadahiko Murata, Takuya Harada

In this paper, we assign an income attribute to each worker in a synthetic population according to Basic Survey on Wage Structure. Using the techniques in this paper, we are able to assign attributes of workers such as working industries and their working status.

Synthesizing Large-scale Household Composition Considering Family Type and Role in Household
Takuya Harada, Tadahiko Murata

Our previous synthetic population method considers only age distribution and age difference between couples by city, town or village. In this paper, we consider the number of household members and their age distributions by Family Types. We are able to synthesize households more close to real ones.

Reconstructing Prefecture-level Large-scale Household Composition Using Parallel Computing
Takuya Harada, Tadahiko Murata

In this paper, we propose a method to parallelize a synthetic population method. We found that it is a key issue how to distribute the statistics to each unit of parallel computing that is employed in population synthesis.
