What will the world look like in 2050, and how will we get there? This comprehensive and compelling book covers the most significant 'megachanges' that are shaping the coming decades, with each of its twenty chapters elegantly and authoritatively outlined by Economist contributors, and rich in supporting facts and figures. It covers all the subject areas you would expect from The Economist: demography; the family; health; culture and social media; climate and the environment; war and peace; democracy and autocracy; religion and secularism; globalisation and the world economy; developed countries and emerging markets; the public sector and tomorrow's company; markets and economic cycles; boom and bust; knowledge and education; technology and communications; science and space; and optimists and pessimists. Megachange is essential reading for anyone who wants to know what the next four decades hold in store.
