Polling Methodology

The field work for surveys is provided by HarrisX, a leading research company specializing in online surveys.

The survey is conducted online within the United States on a daily basis among approximately 1,000 Registered Voters.  The results reflect a nationally representative sample of Americans. Results are weighted for age within gender, region, race/ethnicity, income, political party, and education where necessary to align them with their actual proportions in the population, in accordance with the demographic results of the U.S. Census Current Population Survey. These weighting categories were defined by Scott Rasmussen. Not all HarrisX surveys include all of the parameters included in surveys.

The respondents opt in to take our surveys and some of them are rewarded for their participation.

Typically, data collection is launched by 7:00 p.m. Eastern Time each night. The survey is generally completed by Noon Eastern Time the next day. This schedule allows for appropriate levels of participation from people in all time zones.

Some questions on the survey are repeated every day and reported on a three-day rolling average basis. So, for example, when we report the president’s job approval rating on a Wednesday, it will include data that was collected Sunday night and Monday morning, Monday night and Tuesday morning, and Tuesday night and Wednesday morning.

Other questions are tracked on a weekly or monthly basis. Additionally, every day specific questions are added related to events in the news. These questions, with rare exceptions, are reported based upon a single night of data collection. has an experienced team of research professionals who suggest topics, draft questionnaires, and guide all aspects of the survey process. We are constantly and consciously seeking to supplement rather than simply repeat data collected by other public polling firms. We believe that intentionally exploring contrarian themes enhances the public debate by highlighting other perspectives and providing a richer understanding of the topics at hand (see About Us).

As publisher, Scott Rasmussen (see bio) is ultimately responsible for the survey design, data collection methodologies, the weighting targets, topics covered and the questions asked. The team includes:
