@Lydia_Pintscher
Is this ticket asking for counts of various datatype used in WIkidata? Both URI and literals.
Does wikitech:User:AKhatun/Wikidata_Basic_Analysis#Object help?

@AKhatun_WMF: Basically Wikidata's Properties have a datatype. The possible ones are listed on https://www.wikidata.org/wiki/Special:ListDatatypes. What would be interesting to know is how many statements we have for each datatype so that we can understand how much we'd gain if we consider removing all statements of a particular datatype.
Examples:
- https://www.wikidata.org/wiki/Q2#P31 <- 3 statements for datatype "Item"
- https://www.wikidata.org/wiki/Q2#P7471 <- 1 statement for datatype "External Identifier"
I am not seeing that in the analysis you linked but maybe I am overlooking something.

Ah, datatype of properties.
I am not seeing that in the analysis you linked but maybe I am overlooking something.
The one I listed is for datatype of objects, so you didn't miss anything.
Thank you for clarifying! It should be fairly easy to find out as well :)

It seems it's not that easy. The queries for popular datatypes (including Monolingualtext) time out, see https://w.wiki/4GED. It works for unpopular types like TabularData though: https://w.wiki/4GEG.
