Editing Module:PopulationFromWikidata/doc (section)

== Population data in Wikidata ==
=== Wikipedia - Wikidata links ===
In parallel to development of this module [[User:99of9]] and [[User:Canley]] have been working on ensuring all Australian place Wikipedia articles are linked to corresponding Wikidata items (describing that same place). This has largely been done. This enables the use of this module.

=== Census data ===
Population data has historically been manually entered to individual Wikidata items. Recently (since ~2017) [[User:99of9]], [[User:Canley]] and others have used [[d:Help:QuickStatements|QuickStatements]] to do bulk imports of population data from  Australian Bureau of Statistics datasets. Part of developing this module was to refine the list of metadata (qualifiers and reference fields) that should be imported alongside the population values. 

As at July 2022 the first release of the 2021 census population data has been uploaded for the geographic areas relevant to Australian place Infoboxes. This includes data for Suburbs and Localities (SAL), Indigenous Locations (ILOC) and Local Government Areas (LGA). The Urban Centres and Localities (UCL) data is due to be released in October 2022.

The module requires these qualifiers and reference components to have values in the Wikidata population claim.
* applies to part
* point in time
* determination method
* reference: reference URL
* reference: title
* reference: published in 
* reference: retrieved
* reference: Australian Statistical Geography 2021 ID (optional)

An example of a Wikidata item with a correctly filled 2021 population claim (using Census data) is:[[d:Q2821571#P1082]].

=== Non-census data ===

Bulk uploads have been done for census data. They have not been done for between-census [[d:Q112762464|estimated residential population (ERP)]] or [[d:Q113166910|Data by Region]] figures, for example. These estimates are useful for capital cities, LGAs and regions. 

The module requires that non-census population claims have these components:
* applies to part
* point in time
* determination method
* reference: reference URL
* reference: title
* reference: published in 
* reference: retrieved
* reference: publication date
* reference: Australian Statistical Geography 2021 ID (optional)

An example of a Wikidata item with a correctly filled 2021 estimated resident population claim (not the other population claims) is:[[d:Q11568#P1082]]. 
An example of a Wikidata item with a correctly filled 2020 LGA Data by Region population claim (not the other population claims) is:[[d:Q704257#P1082]].
