From the Penn Library website, a resource for Latin American public opinion:
The Latinobarometers are annual public opinion polls conducted in several Latin American countries, 1995 to present. The 2006 Latinobarometer covered these countries: Argentina, Bolivia, Brazil, Colombia, Costa Rica, Chile, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela, Dominican Republic. The Latinobarometers are designed to complement the other Global Barometer polling projects in African and East Asia.
Latinobarometers typically ask several dozen questions to reveal opinions, attitudes and behavior of 1000 adult residents in each country. A special focus of the Latinobarometers is democracy and democratic consolidation, and individual years also have central themes. Additional information on the Latinobarometers is provided at their website. However, the data sets are not available for free at the website, go through the UPenn Library page for access to those. Each data file is provided in SPSS save format and therefore requires SPSS or other statistical processing software. Data files with PDF-format codebooks are provided in ZIP archive files as delivered by the vendor. PDF-format codebooks are also provided separately as a reference source.
