A questionnaire survey on the definition of homeless people that central governments of OECD countries regularly rely on as well as framework to monitor the scale of homeless problems has been conducted. Results of the survey shows that central governments in several OCED countries do not have their definition of homeless people, and that there is a great disparity in the definitions. In addition, it was found that few countries have established a framework to regularly monitor the number of homeless people. The result indicates that Japan is the countries that has the narrowest definition of homeless people, and one of few countries that have already established the monitoring framework.
