In various wide-area plans and operations including national spatial strategies, regional blocks were granted as higher-level plans after various controversies and conflicts. As the number of people in charge of local area activities decreases, it is unavoidable that local blocks should be reproduced from a bottom-up perspective based on a real connection (contributing to the region through visitation) between each individual and the block. This study applied an inverse estimation of regional blocks through principal component analysis based on a nationwide survey of regional experience seekers. As a result, 11 principal component axes which define the basic national structure were extracted from the relevant population. Furthermore, results showed quantitatively that some regions are involved in some blocks in terms of relation. Some local blocks have no mutual relation. New guidelines were inferred for the formation of practical policies for use in future societies.
