ESTIMATED REACH COUNTING
Definition
A method used to describe the size of a panel or database. Reach estimates may take into account multiple panel members residing at the same physical address or using the same computer or email address. Reach counting is not a generally accepted way to describe the size of a panel, but can be provided as additional information about the composition of a panel. For example, a panel may have 600,000 members, but including additional members of each panelist's household, the total size or "reach" of the panel could be 1.3 million.
