A Note about August 2012 qSearch Reporting

With the release of August 2012 U.S. qSearch data, comScore introduced two important methodological enhancements to our estimates that will affect qSearch data on a go-forward basis. The first enhancement is the incorporation of updated demographic universe estimates based on data from the 2010 U.S. census, which provides an improved accounting of the percentage of the population falling into each demographic segment. The second enhancement was an improvement in comScore’s enumeration survey methodology to better represent persons in cell-phone only households.

Due to the effects of the changes to the August 2012 U.S. qSearch data, comScore’s monthly qSearch press release will limit public reporting to the standard current month rankings and will exclude the month-over-month changes, which include the effects of inorganic increases or declines due to the methodological enhancements. The qSearch press release will resume normal reporting of month-over-month changes with the release of September 2012 data.
