The AmericasBarometer, one of the many and growing activities of LAPOP, is the only survey of democratic public opinion and behavior that covers the Americas. It is an effort by LAPOP to measure democratic values and behaviors in the Americas using national probability samples of voting-age adults. In 2004, the first round of AmericasBarometer surveys was implemented with eleven participating countries; the second took place in 2006 and incorporated 22 countries throughout the hemisphere. In 2008, 24 countries throughout the Americas were again included, and over 36,000 individuals. In 2010, 26 countries were included with Trinidad & Tobago and Suriname added for the first time, and over 43,000 individuals were surveyed. In 2012, 26 countries were included again, and over 41,000 surveys were carried out. The 2014 round, which marks the latest round of surveys of the AmericasBarometer, includes surveys conducted in 28 countries across the Americas and more than 50,000 interviews.
