Template:Population WD
Script error: The module returned a nil value. It is supposed to return an export table.
Template documentationShows the population size of a place, according to Wikidata, together with the year.
{{Population WD}} without argument, shows the population of the current article subject.
{{Population WD|<page title>}} shows the population size of the page title subject stated in the first unnamed parameter (it does not use the Wikidata label). It also works if the article is moved, since it follows the redirection.
The template is intended for population tables of several different places. A purpose of this kind of template is to avoid advanced code in Wikipedia articles, and use a comprehensible property name and article title instead of pid and qid codes. However, the template may also be called with a parameter named qid.
A logged-in user will see a clickable pen next to the value and date. This is helpful in population tables for several different places, to find at which Wikidata page each value can be edited, and where the source and editing history of the value can be found.
An advise is to not replace new values with older Wikidata values.
Usage
The template shows the Wikidata population value of highest rank (typically the most recent reliable value) or, if several values have highest rank, the most recently entered value.
Current page
Example:
{{population WD}}
shows the population of the current article subject.
Articles sharing the same label
The template does not use the Wikidata label. These two places have the same label Stockholm:
{{population WD|Stockholm}}
gives the population of Stockholm: Script error: The module returned a nil value. It is supposed to return an export table..
{{population WD|Stockholm (town), Wisconsin}}
gives the population of Stockholm (town), Wisconsin: Script error: The module returned a nil value. It is supposed to return an export table..
Redirections
The redirection page Stockholm, Sweden also works:
{{population WD|Stockholm, Sweden}}
and gives: Script error: The module returned a nil value. It is supposed to return an export table..
Qid code
A last option is to use the qid code of a place, which however makes the wikicode less comprehensible, but is useful if the place has no Wikipedia article:
{{population WD|qid=q1754}}
results in the population of Lua error in Module:Wd at line 621: attempt to index field 'wikibase' (a nil value). (Q1754): Script error: The module returned a nil value. It is supposed to return an export table..
