To evaluate differences between countries/regions, the classical statistical method is by evaluation of individual question items using hypothesis tests. They cannot be used, however, in surveys in that have a response (outcome). Regression analysis is another statistical approach, but cannot be used to evaluate the influencing factors in the difference in response between countries/regions. Here, we focus on statistical methods for finding differences in international comparison data, namely subgroup identification methods. We examine the usefulness of subgroup identification methods using data on streetscape satisfaction from surveys conducted in Tokyo, Japan and Chengdu City, China.
