When adding an infobox using data from Wikidata, please check for consistency with the article and its references, and to address the inconsistencies observed, which can be done by amending the article or the Wikidata entry, or by supplying a better value to the infobox as a local parameter if this is what emerges from the sources.
This version of {{Infobox person}} retrieves various parameter values from Wikidata if enabled ("opt-in") as long as that information is sourced on Wikidata to a source other than Wikipedia. Editors can provide a local value at the article level to override or prevent specific fields from displaying, i.e., to indicate that those fields are unsuitable for inclusion in that article's infobox. This template has no option/parameter to display unsourced values.

ਮੌਤ

and you should get a Wikidata-filled infobox! (Providing the article is linked to a Wikidata entry containing relevant information!) This will by default only fetch information that is sourced on Wikidata. This is an important safeguard for BLPs. The subject's current age (or age at death) will be calculated automatically provided that the dates are sourced and full (i.e. 12 January 1958 not 1958).
This will prevent the infobox from displaying the fields for occupation or children. |noicon=on will suppress the pencil icons in favour of a single "edit on Wikidata" link at the bottom (see Tolstoy, right).
