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 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 responsible for the commissioning and control of radio audience research in Ireland. The committee is made up of representatives from public service and commercial broadcasters, IAPI (Institute of Advertising Practitioners in Ireland), AAI (Association of Advertisers in Ireland) and the BCI.

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

Yesterday listenership / Reach

Yesterday = Average Day

 

Reach = size of audience “reached” by radio in general or by a specific station.

 

In other words reach = the number of people who listened/tuned into a station yesterday (on average day). It doesn’t matter if they tuned in for 2 minutes or for 2 hours – everyone who listened is counted here.

 

This question basically measures the number of people who have an “opportunity to hear” a radio station.

The figure is calculated by: (number of listeners to Station X / total estimated sample size) * 100

Market share - Minutes

Market Share = Share of all minutes listened (e.g. between 7am and 7pm ) to Irish Commercial Radio. In other words - of all the minutes listened to Irish commercial radio between 7am-7pm , Station A achieves x%, Station B achieves y%.

 

The market share table will always add up to 100%.

 

Market share is a better measure of station loyalty. While reach picks up listeners who flick in and out of the station, share shows the depth of listening to a station.

 

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.
