How can DSR provide usage data for a directory when it has not sampled households within that directory distribution area?
All ratings, regardless of medium, are estimates. Ratings services can neither afford to nor need to survey the entire population in order to estimate what consumers watch, listen to, read, or use. DSR provides estimates that are based on sound statistical procedures that stand up to rigorous scrutiny. DSR’s representative sample provides a solid foundation for estimating directory usage in every ZIP Code in the nation.
