To get an overview of triples, consumed by history and quality data, please use the following query using SPARQL Endpoint of a Project or PoolParty's SPARQL Shell.

SELECT (STR(?nrTotal) AS ?total) (STR(?nrConcepts) AS ?concepts) (ROUND(((?nrConcepts / ?nrTotal) * 100)) AS ?percentConcepts) (STR(?nrHist) AS ?history) (ROUND(((?nrHist / ?nrTotal) * 100)) AS ?percentHistory)
WHERE 
{
 {
  SELECT (COUNT(*) AS ?nrConcepts) 
   WHERE { graph <http://<baseUrl>/<projectId>/thesaurus> { ?s ?p ?o  }}
 }
 {
  SELECT (COUNT (*) AS ?nrHist)
  WHERE { graph <http://<baseUrl>/<projectId>/thesaurus/history> { ?s ?p ?o }} 
 }
 {
  SELECT (COUNT (*) AS ?nrQuali)
  WHERE { graph <http://<baseUrl>/<projectId>/thesaurus/qualityReport> { ?s ?p ?o }}
 }
  BIND ((?nrConcepts + ?nrHist + ?nrQuali )  AS ?nrTotal)
}
