The representativeness of KN panel surveys is attributable in part to the methodology employed by KN for drawing survey samples from the panel itself. Not covered in this paper but addressed elsewhere, the reliability and accuracy of KN panel surveys are also the result of probability-based sampling employed in the panel recruitment stage and panel management practices.  In this brief paper, we describe the statistical techniques used in our within-panel survey sampling methodology and, second, provide evidence of the sample representativeness that is in part a by-product of the sampling method.
