With the release of each survey wave, Resonate is refreshing all existing audiences to use the latest and greatest data available. Audiences, as well as the insight index and composition, are updated to include data from all active surveys. Each time a new survey wave is released, you can expect that your audiences will be updated if new data is available. Both the metrics and the insights will be affected. The index for a given attribute, calculated as the audience reach divided by the online adult population reach, as well as the composition, will reflect all active survey data.
Your analyses will also be updated. Those audiences built with attributes from a survey question that is no longer being asked will not be refreshed.
