Sustainable development frameworks are being developed in response to existing environmental and social problems. In the implementation of the Doughnut model in Geneva arises the question of how to measure social inclusion through a questionnaire. Through a review of the literature on the concept of social inclusion and other related theories, a relational concept of social inclusion emerges. Relations with others matter at three levels: Micro, with close relationships, the support perceived and the regularity of contacts; meso – non-discrimination and participation in specific communities, such as work, sport, cultural or volunteering activities; and macro – trust and participation in a broad society, a country level. The aim is for the questionnaire to include also subjective questions since most of the existing indicators are objective and it is important to combine them also with the perception of the people themselves. This study concludes that the ideal survey consists of six questions, one subjective and one objective for each of the three levels of integration. Existing surveys in Switzerland and in Geneva are analysed, as well how social inclusion is being measured and how this concept is being included in different sustainable development frameworks. This study questionnaire proposal is based on the Statistics on Income and Living Conditions questionnaire applied in European countries; but the data is not available for the canton of Geneva level. Given the summary characteristics of sustainable development frameworks and aiming at representation at canton level, a shorter version of only two questions based on the Enquête Suisse sur la Santé questionnaire is also proposed, focusing on support and participation.
