Arbitron is producing a ratings report for November for the counties affected by Hurricane Sandy that make up the New York Radio Metro.
However the report will be based on three weeks rather than four weeks of data.
The New York Metro includes the embedded Metros of Nassau-Suffolk and Middlesex-Somerset-Union. As a result of the storm, approximately one-third of the targeted usable sample in Nassau-Suffolk and Middlesex-Somerset-Union was unavailable during Week 4. In addition, average daily in-tab rates were substantially lower for Week 4 in these embedded metros than during unaffected weeks in recent currency reports, according to the ratings firm.
Arbitron says these factors, combined with other performance metrics, resulted in its decision not to produce PPM estimates for Week 4 for Nassau-Suffolk and Middlesex-Somerset-Union. Since the New York Metro includes the Nassau-Suffolk and Middlesex-Somerset-Union Metros, the unavailability of these metros impacts the sample performance of the New York Metro.
As a result, Week 4 PPM estimates for New York will not be produced.
November Week 4 Weeklies estimates for all PPM markets other than New York, Nassau-Suffolk, and Middlesex-Somerset-Union are scheduled to release at the same time as November monthly estimates.
The ratings company is not sure what the storm’s affect will be on the first week of December ratings.
