Hi Bináris,
I never said Wikipedias will always agree; in fact, I pointed to science articles, not social or religious articles, as a dominant use-case. In any event, whatever [[wikidata]] pages are transcluded is entirely under the whim and control of a wikipedia. If a wikipedia wants its own (unique) infobox or other item like a chart, then someone logs onto the wikidata host, creates their infobox/chart, and then transcludes that infobox/chart into their wikipedia page. If a given installation has installed the wikidata extension itself, there is no need to logon to another wiki, otherwise it's the same process.

Thanks - john

Are you sure that Wikipedias will always agree in population and religion charts?
