Group Content arises from pooling of resources of several teams. These teams may wish to devote, say, 8 questions to a particular topic, such as religion and politics or tax policy. If 10 teams can agree on 8 Group Content questions, then their questions will be asked on each of their individual Team surveys. Since the individual Team Content is the same for these 8 questions, they have effectively conducted a survey of 10,000 people (10 teams times 1,000 respondents each).
There are opportunities to ask questions particular to individual states if a sufficiently large number of teams are willing to trade questions across samples. (See the discussion under Sample Design.)
