Project country coverage statsI'm trying to write a query that would give some statistics on the number of articles on a particular country's citizens/subdivisions/other in each Wikipedia, but it keeps timing out. Even this query, which only deals with citizens and only lists the top 15, times out:

Use at

PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX schema: <http://schema.org/>
SELECT ( count( ?q ) as ?i ) ?project WHERE {
  ?q wdt:P17 wd:Q30 ;
     ^schema:about / schema:isPartOf ?project .
  FILTER EXISTS { ?project wikibase:wikiGroup 'wikipedia' . }
} GROUP BY ?project ORDER BY DESC ( ?i ) LIMIT 15
