SELECT ?typeLabel (count(distinct ?x) as ?count)
WHERE
{
  ?x wdt:P8 ?type .
  ?type rdfs:label ?typeLabel.
  FILTER((LANG(?typeLabel)) = "en")
}
group by ?type ?typeLabel
order by desc(?count)

Try it out!

    ?item wdt:P8 wd:Q3 .
    ?item wdt:P107 ?wid .
    BIND(IRI(CONCAT('http://www.wikidata.org/entity/', ?wid)) AS ?person )
  }
} AS %people

WHERE {
