RAJAR

RAJAR (Radio Joint Audience Research) is the official organisation for commissioning the measurement of radio audience research in the UK.  It is jointly owned by the BBC and the RadioCentre on behalf of commercial radio. 

Ipsos MORI is responsible for conducting the RAJAR Survey which is Europe’s largest and most complex media audience survey. 

The objective of the Survey is to provide the radio industry with a “gold standard” of audience measurement in order to monitor programmes and provide a universally acceptable trading currency. 

Key features of the Survey are:

• provision of results for 340 individual local, regional and National stations
• audiences by location and platform showing shares by analogue and digital options
• face-to-face recruitment of respondents and the creation of personalised station repertoires
• placement and collection of individual seven day listening diaries an annual adult sample of 130,000 respondents 15+ with continuous fieldwork across 50 weeks
• quarterly production and distribution of results for all stations 

Ipsos MORI has conducted the Survey continuously since it was first awarded in 1992 and the current contract runs until 2011. 

Since 1992, Ipsos MORI has initiated and implemented a wide range of enhancements covering the design, methodology and distribution of results to ensure the Survey continues to respond to the changing requirements of the medium and technology.
