Overview
YouGov is a United Kingdom-based international market research and data analytics company built around online polling, a large proprietary respondent panel, and continuously updated consumer and public-opinion data. Founded in London in 2000 by Stephan Shakespeare and Nadhim Zahawi, the company initially became known for Internet-based political polling and for publishing commentary and survey findings through its own platform and media relationships. It subsequently developed into a broader research and data business serving companies, media organizations, public institutions, sports organizations and political stakeholders. The company’s core operating model combines online surveys with demographic weighting and statistical modelling. YouGov recruits participants to an online panel, collects responses on political, social and commercial subjects, and adjusts the resulting data to improve representativeness. Its panel has been described as comprising more than 24 million people worldwide. This infrastructure supports both one-off commissioned studies and recurring products that allow clients to monitor changes in public attitudes, brand perception, purchasing behavior, media use and audience composition. YouGov BrandIndex, launched in 2005, is one of the company’s best-known offerings. It tracks daily public perceptions of consumer brands across measures such as awareness, consideration, quality, value and reputation. YouGov Profiles provides audience segmentation and media-consumption analysis, while YouGov Signal combines survey findings with digital and social-media indicators. YouGov Safe was introduced to enable consenting participants to share selected behavioral or transaction-related data in a privacy-conscious, GDPR-oriented framework. The company also operates specialist offerings for sports measurement and for the analysis and activation of research data. Political polling remains an important part of YouGov’s public profile. The company has conducted election and referendum research in the United Kingdom and other markets, including work for media partners. Its use of multilevel regression and post-stratification, generally known as MRP, attracted particular attention during the 2017 United Kingdom general election, when its model forecast a hung parliament while many rival polls anticipated a larger Conservative majority. YouGov has continued to apply modelling and weighting techniques to election research, although, like all polling organizations, it faces scrutiny over sampling, turnout assumptions, questionnaire design and interpretation. YouGov expanded internationally through a mixture of acquisitions and organic growth. Purchases and investments brought operations or specialist capabilities in the Middle East, the United States, Scandinavia, Germany, France, Australia, Canada, Switzerland, Turkey and New Zealand. Acquisitions of firms including Polimetrix, Zapera, Psychonomics, Galaxy Research, LINK Marketing Services, KnowledgeHound and Yabble broadened the company’s geographic footprint and added capabilities in political research, consumer panels, research-data management and generative artificial intelligence. The acquisition of GfK’s consumer panel division, completed in 2024, significantly strengthened YouGov’s consumer-panel activities in Europe. The business is listed on the London Stock Exchange under the symbol YOU. Its leadership has included co-founder Stephan Shakespeare, who served as chief executive during two periods and became non-executive chair before returning as chief executive in February 2025. YouGov is a member of the British Polling Council. Its public reputation rests on the scale and speed of its panel-based data, while continuing debate concerns the limitations of opt-in online samples, the effects of incentives, model assumptions and the independence and transparency of political polling decisions.
History
YouGov was established in the United Kingdom in May 2000 by Stephan Shakespeare and Nadhim Zahawi. In its early period it combined Internet polling with a media-oriented editorial presence, publishing contributions from prominent commentators and developing a profile in political research. Peter Kellner joined in 2001, later becoming chairman and then president. YouGov became publicly traded in April 2005 through a listing on the London Stock Exchange’s Alternative Investment Market. That year it introduced YouGov BrandIndex, a daily tracking product designed to measure public perceptions of consumer brands. The company’s first major growth phase relied heavily on acquisitions. In 2006 it bought Dubai-based Siraj, giving it an entry point into Middle Eastern research. In 2007 it acquired Polimetrix in the United States, Scandinavian firm Zapera and German company Psychonomics. Further North American expansion followed with the purchases of Clear Horizons in 2009 and Harrison Group in 2010. YouGov also acquired a minority interest in sports-media data company SMG Insight in 2010 and later purchased the remaining shares in 2018, rebranding the operation YouGov Sport. Political polling became especially visible in the period surrounding the 2010 United Kingdom general election, when YouGov held an exclusive arrangement to provide political polling to The Times. The company also created TellYouGov, an early effort to combine social-media signals with polling analysis. Its later social and digital-data work developed into products such as YouGov Signal. In 2011, YouGov acquired Definitive Insights in the United States and opened an office in Paris, marking a combination of acquisition-led and organic international expansion. The company entered the Asia-Pacific region in 2014 through the acquisition of Decision Fuel. It also launched YouGov Profiles, a segmentation platform that organized information about media behavior, interests and audience characteristics. During the 2010s, YouGov increased its use of sophisticated statistical methods in election research. It applied multilevel regression and post-stratification during the 2016 EU referendum and later used the approach in election modelling. Its 2017 United Kingdom general-election projection became a notable case: unlike many forecasts predicting a substantial Conservative majority, YouGov projected a hung parliament and identified several unexpected constituency results. YouGov continued building its Australian presence through the 2017 acquisition of Galaxy Research, which had conducted state and federal political polling. In 2018, the company consolidated its sports-data activity under YouGov Sport. It entered Turkey in 2020 after acquiring Istanbul-based online research agency Wizsight. During the COVID-19 pandemic, YouGov produced extensive public-opinion research, including a collaboration with Imperial College London examining attitudes and behavior related to the virus and government measures. A new acquisition cycle in 2021 added Canada-based Charlton Insights, Swiss company LINK Marketing Services, Australian firm Faster Horses, financial-data specialist Lean App and Rezonence, which connected access to premium content with survey participation. YouGov also launched YouGov Safe, intended to let participants share selected online-behavior data with consent and within a GDPR-oriented framework. These moves reflected a strategy of expanding beyond conventional questionnaires toward a broader, integrated data ecosystem. In July 2023, YouGov agreed to buy GfK’s consumer-panel division. The transaction was completed in January 2024, alongside a separate acquisition of KnowledgeHound in Chicago, which added research-data search and management capabilities. In August 2024, YouGov acquired New Zealand generative-AI company Yabble. The company has also discussed the possibility of a United States listing or secondary listing, although it indicated that such a move was not being considered in the near term. Leadership has changed over time. Shakespeare served as chief executive from 2010 to 2023, then became non-executive chair, before returning as CEO in February 2025 and replacing Steve Hatch. Kellner left the company’s chair and later broader leadership roles in 2016. YouGov remains an active public company and a member of the British Polling Council. Its business now spans political polling, brand measurement, consumer panels, audience intelligence, sports analytics, research technology and data-enabled consulting. Its principal methodological challenge remains the representativeness and reliability of opt-in online samples, particularly when results are used to make high-stakes political, social or cultural claims.

Controversies
2025
Questions about online polling used in a report on Generation Z Christianity
Commentators questioned the reliability of YouGov survey data cited in The Quiet Revival, a Bible Society report that suggested increased Christian participation among Generation Z. Criticism focused on opt-in online sampling, participant incentives and discrepancies between the findings and other social-attitudes surveys or church statistics.
2022
Dispute over alleged suppression of a 2017 election poll
Chris Curtis alleged that a YouGov poll showing a more favorable result for Labour had been withheld because of political pressure linked to co-founder Nadhim Zahawi. YouGov denied that political considerations caused the decision, stating that concerns about a skewed sample and methodology were responsible. Peter Kellner acknowledged late methodological changes, while Curtis subsequently withdrew the allegation, accepted YouGov’s explanation and apologized for confusion.
