Revisiting the substantiality criterion: From ethnic marketing to market segmentation

This paper examines the meaning and application of the concept of substantiality for consumer market segmentation and target selection with a focus on ethnicity and minority ethnic groups. In contrast with interpretations of segment substance anchoring on some sufficient potential size to justify time and effort involved in planning, the objective is to consider key group dimensions to ascertain potential substantiality. Common criteria proposed to assess substance are essentially an exhortation to assess the value of the segmenting opportunity. An increase in producer surplus meets this requirement but this consideration is done post hoc. The challenge for market segmentation is to assess substantiality a priori. This paper presents a screening approach based on appraising minority ethnic group resources that enables such an assessment and has potential applicability to other consumer subcultures.
