The income per person (or GNI/Population) represents the well being of the population. According to the World Bank, the world economy is divided into the following income groups: Low Income= $825/year or less; Lower Middle Income= $826 to $3,255/year ; Upper Middle Income= $3,256 to $10,065/year ; and High Income= $10,066 or more/year. High and Upper Middle income groups will represent 61% of the world population in 2030 ( 25% in 2004). For example, China and India’s middle class will sharply increase (650 million expected in China by 2030). In turn, this greater middle class will mean a consumption explosion and will boost the world economy. As a result, the percentage of poor people (Lower Middle Income en Low income) will decrease from 75% to 39% and will concentrate in South Asia (Except India) and in Africa. Large segments of the world population will endure a greater poverty than in 2004. The inequalities will however rise; In 2004 the income of the hyper rich ( North America- More than $30,000 per capita ) is about 60 fold the average low income (500). In 2030, it will represent 140 fold.
