92. BOP market - $5 trillion. Total by income segment. (Page 13, The Next 4 Billion: Market Size and Business Strategy at the Base of the Pyramid) Four billion people form the base of the economic pyramid (BOP) – those with annual incomes below $3,000 (in local purchasing power). The BOP makes up 72 percent of the 5,575 million people recorded by available national household surveys worldwide and an overwhelming majority of the population in the developing countries of Africa, Asia, Eastern Europe, and Latin America and the Caribbean – home to nearly all the BOP. This large segment of humanity faces significant unmet needs and lives in relative poverty: in current U.S. dollars their incomes are less than $3.35 a day in Brazil, $2.11 in China, $1.89 in Ghana, and $1.56 in India. Yet together they have substantial purchasing power: the BOP constitutes a $5 trillion global consumer market.
93. Estimated BOP market by sector (Page 29, The Next 4 Billion: Market Size and Business Strategy at the Base of the Pyramid) Sector markets for the 4 billion BOP consumers range widely in size. Some are relatively small, such as water ($20 billion) and information and communications technology, or ICT ($51 billion as measured, but probably twice that now as a result of rapid growth). Some are medium scale, such as health ($158 billion), transportation ($179 billion), housing ($332 billion), and energy ($433 billion). And some are truly large, such as food ($2,895 billion).
