Notice – The figures presented hereafter aim to facilitate the understanding of some indicators on Africa to people statistics discourage. Their objectives are not to present scientific but meaningful information. We tried to be very cautious about selecting our information sources but we cannot guarantee that every data collected in there is accurate. Inversely, all possible mistakes someone could find in graphs cannot be ascribed to those organizations from which we picked up information. We invit our readers to report us every error which remains in spite of our watchfulness. Thank you!
