What I mean is, BBC Radio 1 have a target audience, which is young and so do The TV channel BBC3, now I've seen it mentioned about the fact they have had to change things before due to attracting more listeners/viewers that aren't in the age rage they were expecting, but how do they know the ages of these people that are listening and watching? Surely they only know how many people they are attracting, not the age range on each day? I'm confused, don't know if I'm being dumb lol but would be good if someone could explain it to me.

Sorry about the spelling mistakes (iphone)
I can become quite paranoid over this kind of thing, so would really like to know how they know.

I believe the people that do the TV/Radio ratings collect ratings by givings volunteers a gadget that they note everything they watch/listen to on. They then use some weird maths to take the percentages of what people in their sample group watch/listen to, to represent the whole of the UK. As they have the personal details of said volunteers they can factor things like age into their stats too.

Personally I've always found it a bit suspect-does their sample group REALLY reflect the tastes of everyone in this country? But as we don't have a better system that's the way it is. If every TV or Radio had something built into it that sent exact ratings data back to some faceless government dept people on the internet would only think it was a NSA/Illuminati/Political plot to take over the world. So its possibly better they keep the current system.

It won't be perfect obviously, but a sample of only a few thousand people will be able to give statistics that will be very close to the true stats for the whole country.

Statisticians can work out the number of people that need to be polled to be 99% sure the statistics that they collect are +/-0.1% from the true value for the whole country. It's usually a much smaller number than people expect.
