We then get some very large samples for some important aspects of young people's lives. You can buy the report, of course, but the headlines can be seen on our website.
These aren't really 'national' figures: they come from the changing and to some extent accidental sample of schools taking part in the surveys in any one year. But the population of schools in our databanks are a reasonable match to the national sample, our results usually do match genuinely national samples where we can see an overlap, and so we might be allowed to hope that they are fairly representative of the national numbers where we have no direct comparison.
