Originally proposed at Wikidata:Property proposal/Generic

Done: Indian census area code (2011) (P5578) (Talk and documentation)

Description	code used for an area for calculations in the 2011 census of India
Represents	2011 census of India (Q1861882)
Data type	External identifier
Domain	items about administrative divisions of India (states/union territories, districts, taluks/tehsils/CD blocks/etc., villages)
Allowed values	\d{2,6}
Example 1	Bihar (Q1165) → 10
Example 2	Aurangabad district (Q43086) → 235
Example 3	Deo Block (Q12433979) → 0473
Example 4	Pachmo (Q12436675) → 254385
Source	(items to be created in the near future for each village and town directory and primary census abstract)
Planned use	augment village items with census codes, so that later those who wish to add citations to population figures can have an easier time doing so
Number of IDs in source	at most 1,000,000 (based on the length of a village code being six digits)
Expected completeness	eventually complete (Q21873974)

Motivation

In planning an import of items related to Indian census reports, I have come to realize that the way I've been separating different census codes using P3213 is becoming somewhat awkward, first in having to qualify in each instance the date the code applies to, then in setting up the regex used to verify that codes are legitimate, and then simply due to there being two different schemes (the Permanent Location Code Number (PLCN) scheme from 2001 and the Metadata and Data Standards (MDDS) scheme from 2011) used for the two different years being conflated in a single property. I thus would like to separate P3213 into two properties, one for each code scheme. This new property is intended for use with 2011 codes, and I would like to rename P3213 "Indian census area code (2001)"¹, not just due to the differing scheme but also per the examples initially given by AbdealiJK² when he proposed P3213. There is already a precedent for differing census schemes having different properties by virtue of the existence of Australian Statistical Geography 2011 ID (P4014) and Australian Statistical Geography 2016 ID (P4093) for Australia and OKATO ID (P721) and OKTMO ID (P764) for Russia.

¹ PLCN codes are given alongside MDDS codes in most, if not all, of the 2011 census reports for ease of comparison between the censuses.

² I have not been able to reach AbdealiJK even on Facebook to ask for his opinions on such a measure; @John Vandenberg: do you know of any ways to get in touch with him?
