Survey Methodology:
These surveys were conducted online within the United States between October 7–9, 2020 among 2022 U.S. adults aged 18 and over, April 23–25,2019 among 2029 U.S. adults aged 18 and over, and October 18–20, 2017 among 2112 U.S. adults aged 18 and over, by The Harris Poll on behalf of Blockchain Capital via its Harris On Demand omnibus product. Figures for age, sex, race/ethnicity, education, region and household income were weighted where necessary to bring them into line with their actual proportions in the population. Propensity score weighting was used to adjust for respondents’ propensity to be online.
All sample surveys and polls, whether or not they use probability sampling, are subject to multiple sources of error which are most often not possible to quantify or estimate, including sampling error, coverage error, error associated with nonresponse, error associated with question wording and response options, and post-survey weighting and adjustments. Therefore, the words “margin of error” are avoided as they are misleading. All that can be calculated are different possible sampling errors with different probabilities for pure, unweighted, random samples with 100% response rates. These are only theoretical because no published polls come close to this ideal.
Respondents for this survey were selected from among those who have agreed to participate in our surveys. The data have been weighted to reflect the composition of the adult population. Because the sample is based on those who agreed to participate in the online panel, no estimates of theoretical sampling error can be calculated.
