In general, whereas there has been progress at all levels with regard to democracy, growth and restoring the macro-economic balances in Africa over the past fifteen years, half of sub-Saharan Africa lives on under one dollar a day, and AIDS is threatening the social fabric of the continent. The studies conducted by various organizations (including the African Development Bank and the World Bank) show that, with the exception of northern and southern Africa, the United Nations Millennium Development Goals (reducing by half the number of persons living in poverty and without access to potable water by 2015) will in most cases not be attained. Nevertheless, these same studies indicate that the majority of the African countries can make notable progress to these ends.
