LAPOP's System for Online Data Analysis (SODA)

We offer two alternatives for querying LAPOP databases:

BEGINNER mode: The user can request frequency distributions or cross-tabulations. The user is unable to define filters (I.E., select sub-classes), recode variables, or control for third variables.



EXPERT mode: Beyond the Beginner mode's functions, the user can define filters (select sub-classes), recode variables, and control for third variable effects (e.g., via regression analysis).


For other inquiries can now check preset LAPOP:

PRESET (Developing site) mode. You could get charts, graphs and maps of previously issued queries in the system


This is an on-line querying system to the original databases (micro-data) of the surveys of the Latin American Public Opinion Project (LAPOP), Vanderbilt University.

LAPOP is a project directed by Professor Mitchell A. Seligson, Centennial Professor of Political Science at Vanderbilt University. LAPOP functions as a consortium of academic and non-governmental institutions and individuals across the Americas. LAPOP's principal survey project is a bi-annual regional survey of the Americas called the AmericasBarometer.

LAPOP surveys measure citizen views on system support, political tolerance, citizen participation, local government, corruption, and authoritarianism, and many other topics related to democratic politics and opinion. Surveys have been conducted and are now available at this site for 26 countries in the Americas: Argentina, Belize, Bolivia, Brazil, Canada, Colombia, Costa Rica, Chile, Dominican Republic, Ecuador, El Salvador, Guatemala, Guyana, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Trinidad & Tobago, Suriname, the United States, Uruguay, and Venezuela.

This website allows access to the 130 high quality surveys LAPOP has conducted on topics of great interest to political and social scientists, Latin Americanists, government officials, and interested citizens. Users can query the data free of charge and with no registration. It is possible to access individual country databases and to access the various waves of the America Barometer survey project.
