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.
