The JNLR survey is conducted via in-home, personal interviews, among an annual sample of c16,800 adults aged 15+ in Ireland. The survey utilises the ‘one-day-aided’ recall methodology, whereby the respondent recalls all listening activity for the day prior to interview. A scripted, paper and pen, questionnaire is used by Ipsos MRBI's team of specialist interviewers.
The JNLR survey is representative of the adult (15+) population of the country, the latest estimate of which is derived from the CSO - Quarterly National Household survey.
The JNLR delivers average daily audiences, based on a rolling 12 month database. Analysis of data is conducted at a national, regional and local franchise level and by the main demographic groups for all stations.
The sample is drawn to be representative of the population of each radio franchise area in geographic and demographic terms. Weighting factors are applied at analysis stage to re-align the national sample to known population estimates.
