Item 7.01 Regulation FD Disclosure

On November 9, 2007 Arbitron Inc. (“Arbitron” or the “Company”) will hold a conference call with its Portable People Meter (“PPM”) customers regarding the Company’s progress with its Portable People Meter service. The Company intends to discuss the following issues, among others, during the conference call:

•

Daily and monthly sample size and quality in Philadelphia and Houston, and other information regarding New York PPM pre-currency radio ratings data;

•

The terms of the Company’s previously announced PPM sample size guarantee, including, without limitation:

•

The Company’s proposal to rebate to its PPM customers an aggregate amount equal to the product of:

•

one percent of the net license fee actually paid by the customer for PPM radio ratings in a market for a monthly survey period in which the Company’s delivered average daily in-tab among persons 6+ falls below the threshold established by the Company for that market during the applicable monthly survey period; multiplied by

•

the number of percentage points by which the Company’s delivered average daily in-tab among persons 6+ falls below the threshold established by the Company for that market during the applicable monthly survey period.

•

Rebates will be applied in the form of a credit which will be calculated and reported once per year for each PPM customer;

•

The rebate will apply only to the Company’s syndicated PPM-based radio market report service and respondent level data access. Software license fees and other fees will not be eligible for the rebate;

•

For Philadelphia and Houston the established threshold will be equal to 90% of the Company’s average daily in-tab target among persons 6+ for any applicable monthly survey period;

•

For Philadelphia and Houston the guarantee will be applicable beginning with the October 2007 survey;

•

For New York and all subsequent markets the established threshold will be equal to 85% of the Company’s of the average daily in-tab target among persons 6+ for the first currency monthly survey period, and will increase by one percentage point per monthly survey period thereafter, but no event higher than 90%;

•

For New York and all subsequent markets the guarantee will be applicable beginning with the first monthly survey period of PPM currency in such market; and

•

Update on the progress of panel build-out of markets previously announced to be commercialized in the near future, and other issues related to the transition from diary-based to PPM-based currency.

The slides to be used on the call are attached hereto as Exhibit 99.1.
