El Salvador
El Salvador is the smallest and also the most densely populated country in Central America. It borders the Pacific Ocean between Guatemala and Honduras. It lies on the Gulf of Fonseca, as do Honduras and Nicaragua further south.
It has a population of approximately 5.7 million people as of 2009 on 21,000 km2. The capital city of San Salvador is, by some distance, the largest city of the republic. In 2001 El Salvador dropped its own currency, the colón, and adopted the U.S. dollar instead.
