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. 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.
