Apparently your solution doesn't works because the template "
Données/Toulouse/évolution_population<http://fr.wikipedia.org/wiki/Mod%C3%A8le:Donn%C3%A9es/Toulouse/%C3%A9volution_population>"
doesn't appear in the among the "
dbo:wikiPageUsesTemplate" property values :-(
http://data.lirmm.fr/sparql/?default-graph-uri=&query=select+*+where+{%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FToulouse%3E+%3Chttp%3A%2F%2Fdbpedia.org%2Fproperty%2FwikiPageUsesTemplate%3E+%3Ft}&should-sponge=&format=text%2Fhtml&timeout=0&debug=on
