From a panel organised by MEDIAMETRIE in January-February 1993 during three weeks based on a representative sample of French population, aged 15 and over (4,683 individuals), a treatment has been conducted in order to analyse answers from each participant by : - Duration of listening radio on three weeks - Share of listening dedicated to radio stations of Radio France network. Then, individuals who did not listened to Radio France have been classified into 7 different categories, in which listeners show an homogeneous listening behavior among them : - light radio listeners - light listeners to Radio France - average listeners to Radio France - heavy listeners to Radio France - strong radio listeners - very light listeners to Radio France - light listeners to Radio France - average listeners to Radio France - heavy listeners to Radio France For each level of listening, we describe : - audiences attitudes for different aggregate - socio-demographical profile of listeners. The survey's method by panel enabled us to evaluate public service radio reach. During the survey, half of the French population listened, at least once, one of the radio stations of Radio France network. It was interesting to define different ways of consuming these stations.
