Exhibit 99.1

FOR IMMEDIATE RELEASE

ARBITRON INC. REPORTS 2002 FIRST QUARTER FINANCIAL RESULTS

Revenue up 9.5% over first quarter 2001

NEW YORK, APRIL 18, 2002 – Arbitron Inc. (NYSE: ARB) today announced results for the first quarter ended March 31, 2002.

For the first quarter, the Company reported revenue of $65.9 million, an increase of 9.5% over revenue of $60.2 million during the first quarter of 2001. Earnings before interest and taxes (EBIT) for the quarter were $27.6 million, compared with EBIT of $27.3 million during the same period last year. Net income for the quarter was $14.2 million, compared with $16.3 million for the first quarter of 2001.

Cost and expenses were higher than last year because of planned increased spending related to the RADAR® service, the Portable People Meter initiative, royalties, data collection, and research and development. Net income compared to 2001 declined as a result of interest expense related to the debt incurred in connection with the reverse spin-off from Ceridian on March 30, 2001.

Net income per share for the quarter was $0.49 (basic) and $0.48 (diluted), compared with $0.56 (basic and diluted) per share during the comparable period last year. The 2001 earnings per share amounts have been adjusted to reflect the one-for-five reverse split, which became effective following Arbitron’s reverse spin-off from Ceridian on March 30, 2001. Effective January 1, 2002, the Company discontinued the amortization of goodwill in accordance with generally accepted accounting principles. Had the Company been required to adopt this accounting effective as of January 1, 2001, net income and diluted net income per share for the three months ended March 31, 2001 would have been $16.7 million and $0.57, respectively.

In announcing the results, Stephen Morris, president and chief executive officer of Arbitron said, “Our core business remains solid and continues to grow, even with the challenging economic environment. In the first quarter, we generated near double-digit percentage revenue growth, in part due to revenue from our recent RADAR acquisition. Our net earnings for the quarter were in line with our expectations and we remain on track in terms of our expectations for 2002.”

“Since the beginning of the year, we delivered the first data to our charter customers in our new market of Mexico City and we began the groundwork for further expansion of our diary-based service in that country. We reached an important agreement with our radio network customers that allows us to use our existing diary database to produce the RADAR network audience estimates,” Mr. Morris continued.

“This week, Arbitron signed a contract extension with Infinity Broadcasting Corporation, which gives their stations access to our Winter 2002 quarterly radio ratings until the release

of the Spring 2002 radio survey as well as access to additional services currently provided. Negotiations for a long-term renewal of the Infinity Broadcasting contract continue,” said Mr. Morris.

“We also have made significant progress in our Portable People Meter initiative,” noted Mr. Morris. “We have reached our goal of recruiting 1,500 consumers for the second phase of the U.S. market trial and are getting ready to analyze the station specific ratings that this new phase of the PPM trial is now producing,” said Mr. Morris. “This is the next important step in our efforts to form a joint venture with Nielsen Media Research.”

(1)  Effective January 1, 2002, the Company adopted the provisions of Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets,” which required the Company to discontinue the amortization of goodwill and rather test such assets for impairment on an annual basis. Had the Company been required to adopt the provision of the pronouncement effective as of January 1, 2001, net income and diluted net income per share for the three months ended March 31, 2001 would have been $16,721 and $0.57, respectively. The Company does not expect to have any goodwill impairment charges from the adoption of the new pronouncement during 2002.

(2)  The computations of basic and diluted net income per common share for the three month period ended March 31, 2002 are based on Arbitron’s weighted average shares of common stock and potentially dilutive securities outstanding, respectively. For the three-month period ended March 31, 2001, the net income per weighted average common share computations are pro forma computations based upon Ceridian’s weighted average number of shares of Ceridian common stock and potentially dilutive securities outstanding. In November 2000, Ceridian’s board of directors approved a one-for-five reverse stock split, which was effective immediately after the spin-off. Pro forma net income per common share and weighted average common shares outstanding presented herein have been adjusted to reflect this reverse stock split. The diluted weighted average common shares amounts assume that all of Ceridian’s historical dilutive securities were converted into Arbitron securities.

(3)  EBITDA is presented as supplemental information that management of Arbitron believes may be useful to some investors in evaluating Arbitron because it is widely used as a measure to evaluate a company’s operating performance before interest expense, as well as to evaluate its operating cash flow. EBITDA is calculated by adding back net interest expense, income tax expense, depreciation and amortization to net income. EBITDA should not be considered a substitute either for net income, as an indicator of Arbitron’s operating performance, or for cash flow, as a measure of Arbitron’s liquidity. In addition, because EBITDA is not calculated identically by all companies, the presentation here may not be comparable to other similarly titled measures of other companies.

(4)  Prior to the spin-off from Ceridian Corporation, Arbitron distributed its earnings to Ceridian. Those distributions, together with a $250 million distribution made to Ceridian on the date of the spin-off, gave rise to the stockholders’ deficit. Proceeds from the issuance of long-term debt were used by Arbitron to make the $250 million distribution.
