Marketing research targeting poor consumers has been developing recently. The specific characteristics of these consumers make it difficult to conduct empirical research. This difficulty has raised the question of how to adapt the methods and techniques usually used in marketing. This article provides a multidisciplinary review of the difficulties encountered in addressing people living in poverty and enables researchers to assess this population and anticipate their needs. In addition, based on a literature review of the methods used in 83 empirical marketing studies published between 1990 and 2021, our study provides researchers with a vade-mecum to guide them in their choice of research design. Concrete and detailed recommendations are provided to facilitate their involvement in the field of poor consumers.
