RADIO ONLINE | , ,

Arbitron released a summary of sample quality metrics on Friday for the June, 2009 local market PPM survey report (May 28, 2009-June 249). On average, across 20 PPM currency markets for the June 2009 survey reports, PPM panels delivered 6+ sample targets at 101%, 18-54 at 96% of sample targets, Black Persons 6+ at 102% of sample targets and Hispanic Persons 6+ at 100% of sample targets.

On average, in the eight PPM markets that qualify for Spanish-language weighting, the PPM panels delivered Hispanic Spanish-Dominant sample targets at 124% and Hispanic English-Dominant sample targets at 100%.

Among the 18-34 demographic, the average performance across the 20 markets was 88% of the sample target. By race/ethnicity, Black Persons 18-34 averaged 80% of the sample target; Hispanic Persons aged 18-34 averaged 100% of the sample target and Other Persons 18-34 averaged 85% of the sample target.

In-tab rate for 6+ across the 20 PPM-currency markets for the June 2009 PPM survey averaged 74%. The Sample Performance Indicator (SPI) posted a 19.9% average.

As previously announced, Arbitron has implemented new initiatives designed to help it manage its panels closer to its targets for Persons 6+, while continuing to achieve average sample benchmarks for young adults and Black and Hispanic persons. Arbitron currently anticipates that PPM sample sizes for 6+ will average closer to the target (100 DDI), and that the average DDI for Persons 18-34 will be near 85 during the next few months.
