What is the DoubleDecker™ omnibus survey?
Each month, we administer a single questionnaire to a large random sample of U.S. consumers. The survey covers a wide variety of topics, driven by our clients’ immediate research needs and by DDG’s internal focus.
The omnibus also collects a large battery of demographic information, and the response frequencies to our clients’ questions are cross-tabulated by up to 56 different demographic banner points.
Who are the survey respondents?
In reality, DDG runs two simultaneous omnibus surveys.
- The lower deck is General Population, which collects data from a random sample of 1,000 adult consumers across the United States.
- The upper deck is Seniors, focuses on a sample of 1,000 adults 64 and older.
Differences in survey results are reported using null hypothesis significance testing at the 0.95 confidence level.
