In Japan, household size is shrinking. Since there is a correlation between household size and housing size, progress in household size reduction can be a factor causing a mismatch with existing housing stock. It is required to understand the relationship between single-person households and housing size, but it is important to grasp the current situation according to region by statistical data because the distribution of single-person households and housing by size is regional. On the other hand, when conducting regional analysis using statistical data, data tabulated for each prefecture or municipality is often used, such as the results of the population census by municipality. In analyzing such regional data, it is necessary to pay attention to the “modifiable area unit problem” in which the analysis results differ depending on the size of the regional division and the area to be analyzed. In this paper, we calculate the correlation coefficient of an arbitrary area by moving window method using grid square statistics on the population census and GIS, and evaluate the spatial scale of regional analysis. Furthermore, based on this evaluation, we map the distribution of the relationship between single-person households by age and the total area of housing, and consider the regionality of the relationship between them.
