Gallup World Poll The Gallup World Poll is an ongoing global survey program that measures public opinion, well-being, and social indicators across countries. It produces standardized household interview data used by researchers, international organizations, and policymakers to compare attitudes and behaviors in nations and regions. The program interfaces with scholarly outlets, think tanks, and multilateral institutions to inform debates on development, public health, and political stability.
The project was launched and operated by Gallup, Inc., with ties to institutions such as the United Nations, World Bank, International Monetary Fund, World Health Organization, and the Bill & Melinda Gates Foundation. Its outputs are cited by publications like The Economist, The New York Times, Financial Times, The Washington Post, and academic journals including those from Oxford University Press, Cambridge University Press, Elsevier, and Springer Science+Business Media. Prominent individuals who have referenced the survey include Kofi Annan, Christine Lagarde, Ban Ki-moon, Jeffrey Sachs, and Paul Krugman. The dataset has been used in comparative studies alongside data from Pew Research Center, Eurobarometer, Afrobarometer, and Latinobarómetro.
The program employs standardized questionnaires and trained interviewers to carry out household surveys, often using stratified multistage probability sampling similar to practices recommended by the United Nations Development Programme and the Demographic and Health Surveys (DHS) Program. Interview modes include face-to-face interviews in contexts like India, Nigeria, and China and telephone surveys in countries with widespread landline or mobile penetration such as United States, Canada, and Australia. Questionnaire design draws on psychometric techniques discussed by researchers at Harvard University, Stanford University, Massachusetts Institute of Technology, and University of Chicago. Data weighting and post-stratification reference population controls from national statistical offices including Office for National Statistics (United Kingdom), U.S. Census Bureau, and Statistics Canada.
Coverage spans more than 160 countries and territories, with sampling frames adapted to national contexts from islands such as Fiji and Barbados to large nations like Brazil, Russia, and Indonesia. Sample sizes vary by country to balance precision and cost, with larger samples in countries such as China, India, United States, and Mexico. Fieldwork logistics have involved partnerships with local research firms and oversight by institutions like WorldPop and regional bodies such as the African Union and the Association of Southeast Asian Nations. Sampling challenges encountered in fragile states include operations in areas affected by conflicts like those involving Syria, Afghanistan, and Yemen.
Major reports produced from the data have addressed global well-being, life evaluation metrics, employment trends, and public confidence in institutions. Notable thematic outputs align with agendas from Sustainable Development Goals discussions and analyses used by leaders including Angela Merkel and Emmanuel Macron. Topics highlighted in published reports include global happiness rankings cited alongside work by Ed Diener and researchers at the University of British Columbia, life satisfaction comparisons used by Daniel Kahneman, and metrics relevant to public health assessments by Margaret Chan. Cross-national comparisons have been used in studies alongside datasets from UNICEF, World Food Programme, and Transparency International.
Policymakers at entities such as the European Commission, African Development Bank, Asian Development Bank, and Inter-American Development Bank have used findings for policy design and monitoring. Researchers at universities including Princeton University, Yale University, Columbia University, and University of Oxford have incorporated the data into peer-reviewed articles and dissertations. Non-governmental organizations like Amnesty International, Oxfam, and CARE International have leveraged indicators for advocacy campaigns. Media outlets including BBC News, Al Jazeera, and Reuters frequently cite headline metrics in coverage of global attitudes and crises.
Critiques have focused on sampling biases in hard-to-reach populations, mode effects between telephone and face-to-face interviewing, and potential nonresponse bias discussed in literature from American Association for Public Opinion Research (AAPOR). Methodological debates have referenced work by scholars at London School of Economics, Johns Hopkins University, and University College London regarding measurement equivalence and cultural response styles. Questions about corporate ownership and data access have been raised in forums involving Open Data Institute and Human Rights Watch. Comparisons with alternative surveys such as Pew Research Center and regional barometers sometimes reveal divergent estimates, prompting methodological reflection in the academic community.
The program is managed within Gallup, Inc., with leadership roles occupied by research directors and regional managers who coordinate field operations with contractors and local institutes. Funding sources include corporate contracts, philanthropic grants from foundations such as the Gates Foundation and partnerships with international organizations like UNICEF and World Bank Group. Data licensing arrangements provide subscription access to governments, universities, and private-sector clients including media organizations and consultancy firms such as McKinsey & Company and Boston Consulting Group.
