The first decade of the 21st century witnessed an historic reduction in global poverty and a near doubling of the number of people who could be considered middle income. But the emergence of a truly global middle class is still more promise than reality. In 2011, a majority of the world's population (56%) continued to live a low-income existence, compared with just 13% that could be considered middle income. And though there was growth in the middle-income population from 2001 to 2011, the rise in prosperity was concentrated in certain regions of the globe, namely China, South America and Eastern Europe. The middle class barely expanded in India and Southeast Asia, Africa, and Central America.
