Roughly once a month, Public Opinion Strategies conducts a national survey of 800 registered voters called a national omnibus. These surveys have multiple clients and cover many different topic areas. Our omnibus product allows a client to obtain national data on key questions for less money than conducting their own individual national stand-alone survey. Most clients ask anywhere from one to twenty questions. Screener and standard demographic questions are included in the cost.
Omnibus surveys are generally in the field for three to five days. This is NOT a panel survey in which we re-contact the same respondents. Our omnibus surveys use Random Digit Dial (RDD) sampling methodology, which gives us the confidence that our samples are representative of the national registered voter population. The sample is drawn proportional to the adult voting age population in each state based on statistics obtained from the Census. Quotas are controlled for and based on this data for each state. As well, quotas are controlled for age, gender, and ethnicity across the sample file as a whole. The omnibus includes 25%-30% cell phone only users.
Omnibus surveys are best used when a client has a narrow set of questions, flexible timing, and a need for a national representative quantitative sample.
