The Library subscribes to Data Planet, a dynamic statistical repository. It includes growing numbers of relevant data sets on a single platform with various visualization and analysis capabilities, and is fairly easy to cite. I recommend exploring the various data available for Latin America by country through the appropriate DataPlanet LibGuides.
