The English webpage of CBS on methodologies is here but is not worth much. The Dutch one looks very extensive.
Not my cup of tea, though.
Recent estimates are based on those 5000-man polls, and seem to be self-reported. Thus the diagram in your diary is consistent (coming from the same polls). The pdf mentions that the poll method, too, has been criticised: differential willingness to answer pollsters' question could be a factor. They argue that these criticisms are countered by some studies on second-generation immigrants, and that weighting can compensate the effect; however, I am not sure I understood their argument. *Lunatic*, n. One whose delusions are out of fashion.

To be more explicit: the article seems to imply thst unwillingness or inability (due to language) to answer polls is a problem chiefly among first-generation immigrants. I don't get how studies on the secularisation of second-generation immigrants enables to control that in any way by weighting. But, I only read via Google trnalate -- Nomad, could you read that section (chapter 4, section 3, page 36-37) more thoroughly and 'report' if you 'got' more out of it? *Lunatic*, n.
