BBC Updates Nicaragua Profile
The BBC has a set of country profiles that tend to be relatively good. That is, they tend to present the facts rather than show bias. They have just updated their Nicaragua profile.
I am not sure what the changes are but it is a good introduction to Nicaragua. Note that when you go to the page you see an overview. There are more details by clicking on the tabs.
Never rich in the first place, Nicaragua is striving to overcome the after effects of dictatorship, civil war and natural calamities, which have made it one of the poorest countries in the Western Hemisphere.
