Bottom of the pyramid

The bottom of the pyramid, bottom of the wealth pyramid, bottom of the income pyramid or the base of the pyramid is the largest, but poorest socio-economic group. In global terms, this is the 2.7 billion people who live on less than $2.50 a day.^[1]^[2]

Management scholar CK Prahalad popularised the idea of this demographic as a profitable consumer base in his 2004 book The Fortune at the Bottom of the Pyramid, written alongside Stuart Hart.^[3]
