In July 2015 the Inter-American Development Bank (IDB) published the report, “A Rising US$750 Billion Market: Unlocking Opportunities at the Base of the Pyramid in Latin America and the Caribbean.”
The report “presents information about the size of the base of the pyramid (BOP) market, its socio-economic characteristics, spending patterns and demand-related factors, with statistics about BOP consumer preferences.”
