All data are copyrighted by the Latin American Public Opinion Project (LAPOP) and may only be used with the         explicit written permission of LAPOP, normally via a license or repository agreement (see our web page for         instructions, www.LapopSurveys.org). Data sets may never be disseminated to third parties.
All data are deidentified and regulated by the Institutional Review Board (IRB) of Vanderbilt University. They         may be used only by those who have fulfilled all IRB requirements.
Important note: This data set contains a variable called “WEIGHT1500” which should be activated to produce       representative national results. The weight variable can be activated through the svy setting: svyset upm       [pw=weight1500], strata (estratopri). In this case, all STATA commands should use the pre-fix svy (for example svy: mean       q2 or svy: tab etid ur).
For more information and details about the sample design, please consult the technical and country reports         through a link on the LAPOP website: www.AmericasBarometer.org.
