The Netpop syndicated study is based on an online survey of over 4,000 respondents per country who are members of research panels and thirteen years of age or older. Respondents are selected using a proprietary sampling process to ensure that participants of the survey are representative of the Internet population in the target country based on age and gender.

Respondents are asked one question to identify those who usually access the Internet via a high-speed or broadband connection (any connection greater than 56 kilobits per second). Based on a randomly chosen sample of this size (N= 4000), there is 95 percent confidence that the results are statistically accurate to within 1.55 percent of the entire broadband population if the entire population had been polled. The survey is fielded annually. The first Netpop survey was fielded in August 2006.
