(CNN) -- With the passing of Nelson Mandela it might be timely to put aside out-of-date and ill-informed views of Africa, and see it the way Africans seem to: With a high level of optimism. Two-thirds of respondents to a CNN survey of more than 9,000 people across South Africa and 19 other African countries say they feel more confident about the future than when Mandela came to power. Corruption tops their list of fears -- particularly in Nigeria -- but generally they believe their leaders are "doing their best." The survey, conducted on smartphones, PCs and web-enabled feature phones, was an attempt to give a sense of the mood of Africans about their future and Mandela's legacy.
