The challenge to maintain sample quality in NRS type print surveys has never been greater with rapidly and differentially declining response rates. We can little afford to aggravate this situation by acceding to demands for more and more data 'single source' from the respondent. Increasingly we will be faced with having to treat our primary quality sample/interviews as more of an establishment survey providing a 'skeleton' onto which we subsequent 'hang' a wide range of additional data collected via cheaper means with less rigorous sampling and more convenient research designs.
