Length of Tenure of Leaders Around the World

Gallup has released a graphic displaying the staying power of leaders in countries across the globe.  The data investigates how long individual leaders have remained in power on a country-by-country basis since 1945.  Countries in North America, South America, and Europe all had the greatest turnover rates of leaders.  On the other hand, the Middle East had the least number of changes in leadership; leaders averaged over eight years in power.  This region was followed closely by Africa, which has an average of more than seven years.  Leadership in a number of countries in Asia have also enjoyed longer staying power.  Oman has seen the least number of leaders, with only two since 1945.
