The Material and Social Deprivation Index (MSDI) was created at the end of the 1990 with the aim of measuring deprivation among Quebecers and Canadians at the small-area level.1,2 The MSDI consists of specific socioeconomic characteristics of the population living in a small area. It has often been used as a proxy (substitute) for lacking information on socioeconomic status of individuals in administrative databases. The index facilitates the documentation and identification of the presence of inequalities in health and health system use associated with inequality in access to material and social resources. In a larger perspective, the MSDI has been used for decision-making and public resource allocation in regions and local communities.
The MSDI has the aim of characterizing and highlighting the deprivation at the small area level. This information is useful for regional resource planning in the health and social services system. More specifically, the MSDI can be used for research on social inequalities in health, monitoring of their evolution, the elaboration of public policies and programs, for resource allocation and the evaluation of services.
The MSDI is composed of two dimensions. The material deprivation involves deprivation of the goods and conveniences that are part of modern life, such as adequate housing, possession of a car, access to high speed internet, or a neighbourhood with recreational areas. This deprivation marks the consequences of lack of material resources associated with low education, insecure job situation and insufficient income. Social deprivation refers to a fragile social network, starting with the family and encompassing the community. It is characterized by individuals living alone, being a lone parent and being separated, divorced or widowed. The MSDI groups six indicators chosen for their relationship with health and either one of the two forms of deprivation.3,4,5

A survey to better serve the users of the index of material and social deprivation
In order to better understand the use of the MSDI and the user satisfaction, we created a survey in March 2018 for the index users in Canada. The results revealed the relevance of this tool to measure deprivation at the small area level and the need to rethink the index’s composition and adequacy for sociosanitary regions with varying characteristics.
