Gallup World Poll

"The Gallup World Poll (GWP) is a large cross-country household survey, interviewing more than 100,000 households in over 150 countries, annually or biennially in most countries since 2006." (Clausen et al. 2011, p. 213)

Questionnaire: http://media.gallup.com/dataviz/www/WP_Questions_WHITE.pdf

Survey Methodology: http://www.gallup.com/poll/105226/world-poll-methodology.aspx

Data access seems to be provided by Gallup Analytics (not clear if it allows access to the respondent-level data, though).

Used by:

• Deaton (2008), who investigates the relationship between per capita income and subjective well-being across the world, by using the 2006 poll.
• Clausen et al. (2011), who find a negative correlation between experiencing corruption and having confidence in public institutions.
• Steptoe, Deaton, and Stone (2015), who investigate the relationship between age and subjective well-being across the world.
