Many Western leaders are getting younger even as their countries age

THE developed world is getting older. But oddly enough, its leaders are getting younger. The chart shows the average age of the leaders of four Western countries (America, Britain, France and Germany) since 1950. In the 1950s, voters were happy to elect venerable leaders like Winston Churchill and Konrad Adenauer. The election of Jack Kennedy was the first sign that the cult of youth was flowering but then came the dominance of Ronald Reagan and Francois Mitterrand in the 1980s. Now the West's leaders, including 40-somethings Barack Obama (just) and David Cameron, have never been younger. If the trend continues, the leaders will end up younger than the average citizen.
