The Base of the Pyramid (BoP) is a socio-economic concept that allows us to group that vast segment – over four billion – of the world’s poorest citizens. They constitute an unserved market blocked by challenging barriers that prevent them from realizing their human potential for their own benefit, those of their families, and that of society at large. Technically, a member of the BoP is part of the largest but poorest group of the world’s population, who live on $ 4 a day or less per person. The BoP is typically excluded from the modernity of our globalized civilized societies, including consumption and choice as well as access to organized financial services. The four billion people at the Base of the Pyramid are certainly not a monolith. They can be segmented in various segments, from poor to extremely poor. The extremely poor (approximately one billion people who live on less than $ 1,25 a day per person) can be referred to as the ‘Bottom of the Pyramid.
