How UK radio figures are worked out

Congratulations to commercial radio on great Q3 RAJAR figures.

Some key highlights include a 2% increase in reach (amounting to 689,000 more listeners), a total hours spent increase of 2.4% and the fact that commercial radio reaches 65% of the population each week (34.6 million people).

Radio listener figures are produced by RAJAR. But what is RAJAR? What does it stand for? And how does it compile that all important data? Find out here via Media.info
