The list below contains the current UAS sample batches. Please note that, for most sampled respondents, the recruitment process takes approximately six months from initial contact to their first login to the UAS survey page. For some respondents, it may take even longer before they become UAS members. For more recent batches, the response overview may reflect results that are not yet complete. As a general guideline, batches for which recruitment began more than one year ago may be considered complete. Please also note that the list below is updated regularly as new sample batches are added. To learn more about a specific batch and view its response details, simply click on the batch name.
All percentages reported below are calculated relative to the total number of surveys mailed, excluding surveys sent to addresses that were subsequently determined to be non-existent or invalid (e.g., business addresses). Participation and attrition statistics for each batch are based solely on the household member who first completed and returned the recruitment survey and subsequently joined the UAS (the primary respondent). Any additional household members who later joined the panel (the added members) are excluded from these calculations.
As of January 24, 2024, the UAS revised its definition of active panel membership and updated the detailed tables for each recruitment batch accordingly. This change affects only new members who have completed the My Household demographic survey but have not yet completed any additional UAS surveys. Prior to this change, these participants were considered inactive until they completed at least one additional UAS survey. Under the revised definition, participants are considered active members once they have completed the My Household survey. They are therefore included in the My Household dataset of active participants and in the “Active Panel” section of the detailed recruitment tables below.

A random subset of the sample received an envelope addressed as 'Name or Current Resident' ('Current Resident' only if no name available). A random subset of the envelopes had a colorful label.
