Fall 2006 Response Rate and Sample Representation Initiatives

Pre-Placement Enhancement
Effective Fall 2006, all households with a mailable address at the time of selection receive a letter and pre-placement premium. Pre-placement postcards are no longer sent.

Minimum Premium Increases in Select Markets
In select markets, the minimum diary premium provided to survey respondents increases effective Fall 2006.

Special "Thank-You" Premium to Black, Hispanic, and Young Male Households
Households that meet Arbitron’s Differential Survey Treatment (DST) criteria—including Black, Hispanic, presence of Male 18-24, and presence of Male 25-34—receive a cash “thank-you” (prior to receipt of their diaries) for agreeing to participate in the radio survey. Effective Fall 2006, an increased premium is provided in select markets to households in which the household contains at least one household member who is Black or Hispanic, or who is a Male 18-24 or 25-34.

In additional select markets without an HDBA, households that contain at least one Black household member will receive a special “thank-you” premium. In additional select markets without an HDHA, households that contain at least one Hispanic household member will receive a special “thank-you” premium.

Special Premiums in Hurricane-Affected Markets
Households in markets eligible for Arbitron’s “Promised Incentive” initiative are advised that they will receive a cash premium for each returned diary. Effective Fall 2006, households in New Orleans and Biloxi-Gulfport-Pascagoula containing at least one household member who is Black or Hispanic will receive the maximum “Promised Incentive” premium currently in use.

In addition, effective with the Fall 2006 survey, non-Black and non-Hispanic households with a young male present (18-24 and 25-34) in New Orleans and Biloxi-Gulfport-Pascagoula will receive a special premium with the post-placement letter.

These initiatives replace specific “thank-you” premiums previously offered in those two markets.

Diary Enhancements

Changes to Instruction Page
Effective with the Fall 2006 survey, the instruction page on the inside of the diary cover is modified to incorporate Internet/satellite instructions.  These changes include a modification to the language describing the term “listening,” as follows:

“Listening” is any time you can hear a radio station —whether you choose the station or not. You may be listening to a radio on AM, FM, Internet or satellite. Be sure to include all your listening.

In addition, the instruction “If you listen over the Internet or to a satellite radio service, please include the station name or channel number” is added following the instruction “Write the call letters, dial setting or station name. If you don’t know, write down the program name,” and references to “Internet” and “satellite” are added to the checklist and sample appearing on the inside cover of the diary.

Metro Market Profile Information

Magazine/Newspaper Circulation Data and Vehicle Registration Data
As a service to subscribers, Arbitron provides magazine and newspaper circulation data and vehicle registration data in the "Metro Market Profile" section of the Radio Market Report (Arbitron eBookSM). The Spring 2006 Radio Market Report sourced magazine and newspaper circulation data as current to June 2006. Please note that, in some instances, these data were instead current to December 2005. The Spring 2006 Radio Market Report sourced vehicle registration data in all instances as reflecting October to December of the 2006 model year. Vehicle registration data, in some instances, instead reflected January to June of the 2005 model year. For the Fall 2006 Radio Market Report, magazine and newspaper circulation data and vehicle registration data will be updated for all reported markets.

Service Enhancements

Small Market Arbitron eBook and Maximi$er®/Media Professional® Estimates to Conform More Closely
In markets that are part of Arbitron’s Condensed Market Service initiative, audience estimates reflect a two-book average of the current (Spring or Fall) survey and the most recent previous (Spring or Fall) survey.

Total Line Reporting

Multibook Total Lines Available in Maximi$er/Media Professional
Starting with the Winter 2006 survey, Arbitron began offering Total Line Reporting to stations that simulcast 100 percent, including commercials. Audience estimates for simulcast stations that request Total Line Reporting are reported in a combined total line with the call letters of the primary station (as selected by the simulcast combo).

During the initial survey in which a combo receives Total Line Reporting, prior-survey estimates in the Radio Market Report (Arbitron eBook), TAPSCAN™, and third-party-processor data will reflect listening to only the primary station. Multibook averages during a combo’s initial survey will reflect one survey in which estimates for all partners are combined, averaged with listening in prior surveys to the primary station alone.

Subscribers to Arbitron’s Maximi$er and Media Professional services can produce multibook Total Line estimates for these combos simply by building a combo (in any survey prior to the start of Total Line Reporting) and selecting that combo for each survey in the multibook period.

Subscribing agencies and advertisers that do not have access to Maximi$er or Media Professional may obtain multibook Total Lines from station subscribers to Maximi$er or Media Professional, or may calculate multibook Total Lines using an Excel^TM worksheet that Arbitron has created for that purpose. A sample worksheet is available at the Arbitron Web site at:
