居住期間

研究成果の概要 (英文) : Duration of residency at the current domicile table of the population census is classified into the six categories: “since birth”, ”less than a year”, ”1 to less than 5 years”, “5 to less than 10 years”, “10 to less than 20 years”, and “more than 20 years”. Inclusion of the heterogeneous category “since birth” brings about misleading results in terms of the distribution pattern of the duration of residency. We classified population that fall in that category by age using the individual census records. Comparison of the current and new results suggests that these two sets of tables differ among population attributes. As for the individual-based data integration between census and administrative records, we proposed data matching by segmenting large scale datasets using spatial information. Despite the limited number of common variables which share donor and recipient datasets, we could achieve satisfactory results in terms of data matching.
