I am rather puzzled by some of the attitudes displayed in this discussion.
It would have thought that information from Netherlands Statistics meets the requirements for inclusion in Wikidata. It is a primary source of high-quality, notable information. Further much of the information is related to existing Wiki... pages. Each time I consider this I think "Wouldn't it be nice if [some bit of information from Netherlands Statistics] was available on [some Wiki... page]?" Wouldn't it be nice if the populations of all Netherlands populated places in Wikipedia automatically had the most-current population information sourced from Netherlands statistics? Wouldn't it be nice if summary economic information about the Netherlands was similarly automatically updated?
Of course, a national statistical office gathers a lot of data, and much of it may not be of general interest. So, perhaps, not all of the Netherlands Statistics information should be automatically imported into Wikidata. Maybe instead there should be a way for this information to be accessible via Wikidata so that it can be easily used when creating Wiki... pages.
How to make this work? Good question. There are a number of issues that have to be worked out, including resource consumption issues, user interface issues, and information organization issues that go beyond linked data issues. Maybe Netherlands Statistics can help, particularly if the Wikidata community was enthusiastic about collaborating with them instead of just again saying "Too much information".
