Nigeria and Nigerian issues tend to do badly on global comparative lists and indices. For instance, Lagos, Nigeria was the fifth worst city in the world on the Global Liveability Index in 2010. On the 2009 Mercer Cost of Living Index, Lagos was one of the most expensive cities in the Africa/Middle East region. The country has also consistently been ranked as one of the most corrupt in the world by Transparency International. And now, the 2011 Prosperity Index is one more list to add to the list.
