Drawing on collaborative research from a distinguished team at Harvard and Manchester universities,The Age of Obamaasks how two very different societies are responding to the tide of diversity that is being felt around the rich world.Guardianjournalist Tom Clark, Robert D. Putnam -- best-selling author ofBowling Alone -- and Manchester's Edward Fieldhouse offer a wonderfully readable account. LikeBowling Alone,The Age of Obamamixes social scientific rigor with accessible charts and lively arguments. It will be enjoyed by politics, sociology and geography students, as well as by anyone else with an interest in ethnic relations. Injustice, it turns out, still blight lives of many UK and US minorities -- particularly African Americans. And there are signs the new diversity strains community life. Yet in both countries, public opinion is running irreversibly in favour of tolerance. That bodes well for the future -- and suggests a British Obama cannot be ruled out.
