Total weekly hours represents the total amount of listening to this radio station. This is affected by the total amount of weekly listeners, or how long each audience member listens for. Hours is normally the most important number for advertising sales.
Total weekly listeners - total reach - represents the total amount of people who tune in to this radio station. A 'listener' is counted as an adult 15+ who listens for at least five minutes.
Hours per listener shows how long people who tune in to this radio station stay listening. This is useful to work out whether the audience likes what they hear: or the consistency of the station sound.
Total market share shows how strong radio station is against other radio stations available. Since 1999, there have been many more radio stations launched, so total share will have decreased for most stations.
While not directly related to the radio output, the survey area population shows how many people live in the survey area that the above figures are based on. Sudden changes to this figure normally represent a change in the survey area, which is requested by stations themselves, reflecting a change in transmission or programming, and will affect the above figures. Otherwise, a slow growth reflects the growth in UK population.
From the US?
Howdy! We don't do AQH figures in the UK; but our figure for weekly 'reach' is roughly the same as your weekly 'cume'. TSL is similar to our 'hours per listener' figure. And, a TSA in the US is the same as a TSA here. (You say tomato, we say tomato.) Of note: UK figures are based on a full 24 hour day, and a 7 day week - and the above figures measure radio listening on all platforms, including our digital radio and internet platforms.
