Internet Research Bureau
We worked closely with three independent survey firms – Datafolha in Brazil, Internet Research Bureau in India, and Kantar in the US and the UK – to poll samples of approximately 2,000 respondents per country to reach populations broadly representative of each country’s overall population. Surveys were conducted online in all but Brazil, where respondents were interviewed by telephone and randomly selected on the basis of their cell phone numbers.
