JNLR

Please find below a brief description of the Joint National Listenership Research (JNLR) survey.

Objective
The objective of the Joint National Listenership Research (JNLR) survey is to provide reliable estimates of audience to both National, Regional and Local Radio, as a basis for the planning of advertising schedules. The research is carried out by TNS/mrbi for the JNLR Committee.

JNLR Committee
The JNLR Committee is the organisation responsible for the commissioning and control of radio audience research in Ireland. It comprises representatives of RTE, Today FM, the BCI, IAPI (Institute of Advertising Practitioners in Ireland) and AAI (Association of Advertisers in Ireland) - i.e. all Broadcasting Organisations; the Advertising Agencies; and the major Advertisers.

Research Results
The research is broken down into two main parts, listened yesterday and market share.

Yesterday listenership

Yesterday listenership indicates the percentage of the total sample that tuned into a station any time yesterday. For example, in July 2003/June 2004 the national sample size for Ireland was estimated to be 3,192,000. 447,000 tuned into Station X so the listenership figure was 14%. This is regardless of the actual amount of time spent listening to the station. This was calculated by: (number of listeners to Station X / total estimated sample size) * 100

Market share

The market share figure denotes the percentage presence that a station has in any given franchise area. This percentage is reached by dividing the total number of minutes a station was listened to in any area by the total number of minutes that all radio was listened to in that area and multiplying by 100.
