Google Consumer Surveys Presidential Poll Fielded 9/15-9/16 Results, Crosstabs, and Technical Appendix
1
This document contains the full crosstab results for Red Oak Strategic’s Google Consumer Surveys Presidential Poll, fielded September 15th through 16th, 2016. Question 1 is a screening question, so we report the simple unweighted distribution of answers. For the following questions, all crosstabs are subsetted to respondents who are "somewhat" or "very" likely to vote, with weighting based on age, gender, and region so the sample better reflects the demographic distributions of the United States population of Internet users. Following the crosstabs, a technical appendix contains information on weighting, margin of error and other aspects of the survey. Q1 [Screening Question]: "How likely are you to vote in the November US Presidential Election?" Very likely 66.6% Somewhat Likely 8.0% Not Likely 8.2% Not Registered 8.6% Other / Don’t Know 8.5% Results for questions 2-7 reported from sample of respondents who are "Very Likely" or "Somewhat Likely" to vote, with weighting based on age, region, and gender. Q2: "If the US Presidential election were held today, who would you vote for?" Results from previous survey (fielded 9/1-9/2) displayed in middle column, with difference from current poll results in right column.

Technical Appendix Weighting and Coverage Error The survey is weighted over age, gender, and region in order to approximate the typical Internet using population of the United States. Google provided these demographic characteristics for respondents based on their IP address and online behavior, and Google also constructed the weightings based on these characteristics. Any respondents for whom gender, age or region could not be imputed were not included in our final sample. This population without demographic data amounted to 316 out of 1517 respondents to our survey. This survey’s main source of coverage error is that it excludes members of the population without access to the Internet or a smartphone. Statistical Error and Sample Size The margin of error is reported on a question-by-question basis, in line with suggestions from both the American Association for Public Opinion Researchers and the practices of established polling firms.2 To determine the margin of error for each table, we take the maximum size of one half of the 95% confidence interval for each cell in the table with a substantive response (i.e. not Don’t know / Other). We then multiply this number by the design bias, which in this case is 1.06.3 In other words, we believe that there is 95% chance that the true value of these estimates for the general population is within the margin of error of our reported number. Total surveyed population of likely voters with demographic data N = 914. However, since all of these tables subset the population in various ways to produce the estimates for each cell, we report sample sizes on a per table basis as well. For tables which break down 2016 preference by demographic characteristic and therefore use smaller samples to estimate cells, the error for those cells grows accordingly. Response Rate The response rate for this survey was approximately 5.83%. After running our survey, we were able to compute the percent of people presented with the survey who answer the first question, and then the number of people who continued on to each subsequent question for the survey. We could then multiply these values to determine the overall response rate.
