Radio audience measurement is evolving and has become RAS - Radio Audience Study

Press release

In consultation with market players, Médiamétrie announces an evolution of the benchmark measurement system for radio (previously 126,000 Radio/Médialocales).

Since September 2021, radio audience measurement, now known as RAS - Radio Audience Study, is based on a renewed, optimised and more competitive reporting-based telephone survey, while retaining the soundness that sets the standard on the market. It now relies on a unique base of respondents who are representative of the population for national and local measurements..

This new system supports people's changing lifestyles, with more than 70% of calls made on mobile phones. It also has benefits in terms of accuracy at local level, with an increase in the number of interviews in Ile-de-France, a key area for the market, a scope extended to all mainland French departments (compared to 72 previously, excluding Ile-de-France) and almost one hundred urban areas.

In the words of Julien Rosanvallon, Deputy Managing Director, Médiamétrie:

“France is one of the countries with the finest data to measure Radio media. A large reporting-based survey like RAS meets the highest international precision standards. This development of our benchmark measure fits into a real dynamic. Offering a a system based on a strong consensus, which takes account of the plurality and diversity of the French radio landscape over the whole of France, is at the heart of Médiamétrie's DNA. This also testifies to our willingness to listen to the market and support our customers in their decision-making, in a time of transformation for the media ecosystem.”
