Yes. Zencity collects a representative sample of opinions from the population in any geographic area surveyed while minimizing potential sources of statistical bias. Zencity uses proprietary technology to track the demographic representativeness of its samples in real-time and make corresponding adjustments to ad targeting to maximize representativeness. In communities where many residents are not native English speakers, questionnaires are available in multiple languages and reach out to potential respondents in their native languages.
Zencity uses the annually-updated U.S. Census American Community Survey data to set response targets for each geographic area based on five different variables: race, age, sex, education level, and household income. Based on self-reported demographic data collected in the survey, they track the demographic representativeness of the respondents in real-time and make adjustments to obtain a closely-representative sample.
