AmericasBarometer Surveys vs. Others in LAPOP
The AmericasBarometer surveys (those conducted in 2004, 2006, 2008, 2010, and 2012) have a common "core" questionnaire for each year's surveys. Each "wave" of the survey (meaning 2004, 2006, 2008, 2010, or 2012) has a specific theme, that is, sets of questions that differ from year to year. But each wave has many of the same questions each time, so that they are comparable across years and countries.
A sub-directory containing the AmericasBarometer Core Questionnaires may be found on the download site (see Download Instructions for that link).
Other LAPOP Surveys
Outside of the AmericasBarometer surveys, a number of the core items (e.g., system support, tolerance) are identical or very close, all the way back to 1978 in Costa Rica. However, pre-1990, the samples were often not national in scope, so the question could be the same, but the sample different. If you have questions about a specific survey or item, please contact LAPOP directly (see link below).
U.S. and Canada
Americans and Canadians are polled to enable comparisons of their views about their own political systems with those of Latin Americans.
LAPOP provided only one year's data with all countries merged, 2012. This is provided in the Merged directory. The usual presentation is an individual country for an individual year, e.g., 2006 Bolivia.
Each base directory will include:
Most questionnaires are in Spanish or the local language, of course. Some surveys will include a second questionnaire in English but not all. Technical documentation is all in English.
While the documentation often cites publications in which survey results are summarized, the University Libraries is not guaranteed to own these publications.
