Elle interroge les Fran\u00e7ais sur la d\u00e9centralisation, le f\u00e9d\u00e9ralisme et les d\u00e9coupages r\u00e9gionaux. Sur la question bretonne, l&#8217;Ifop publie trois r\u00e9sultats distincts :<\/p>\n<ul>\n<li><strong>62 %<\/strong> d&#8217;opinions favorables au rattachement en Loire-Atlantique ;<\/li>\n<li><strong>52 %<\/strong> dans les quatre d\u00e9partements de la Bretagne administrative ;<\/li>\n<li><strong>56 %<\/strong> \u00e0 l&#8217;\u00e9chelle des cinq d\u00e9partements de la Bretagne historique.<\/li>\n<\/ul>\n<p>Le soutien \u00e0 la r\u00e9unification dans le p\u00e9rim\u00e8tre historique est compar\u00e9 \u00e0 <strong>44 % en 2012<\/strong>, soit une progression de douze points selon les r\u00e9f\u00e9rences retenues par l&#8217;institut. Cette comparaison entre enqu\u00eates ne signifie pas qu&#8217;un m\u00eame groupe de personnes a chang\u00e9 d&#8217;avis.<\/p>\n<h2>Comment le sondage a-t-il \u00e9t\u00e9 r\u00e9alis\u00e9 ?<\/h2>\n<p>L&#8217;Ifop a interrog\u00e9 <strong>9 689 personnes majeures<\/strong> r\u00e9sidant en France m\u00e9tropolitaine par questionnaire en ligne, du 25 au 30 septembre 2026. La repr\u00e9sentativit\u00e9 de l&#8217;\u00e9chantillon national repose sur la m\u00e9thode des quotas, avec une stratification g\u00e9ographique.<\/p>\n<p>Le d\u00e9tail repris dans la publication consacr\u00e9e \u00e0 la Bretagne porte sur <strong>753 r\u00e9pondants des cinq d\u00e9partements historiques<\/strong>, dont 223 habitant la Loire-Atlantique. Ce sous-\u00e9chantillon est beaucoup plus limit\u00e9 que celui de l&#8217;\u00e9tude nationale. Par cons\u00e9quent, les r\u00e9sultats territoriaux doivent \u00eatre lus comme des estimations issues d&#8217;une enqu\u00eate, avec une incertitude statistique et des effets possibles de formulation de la question.<\/p>\n<p>La pr\u00e9sentation compl\u00e8te des th\u00e8mes et de la m\u00e9thode figure dans <a href=\"https:\/\/www.ifopgroup.com\/?p=96906\" style=\"color:#5532F0;font-weight:bold;text-decoration:underline\"><strong><u>l&#8217;\u00e9tude publi\u00e9e par l&#8217;Ifop<\/u><\/strong><\/a>.

Le d\u00e9bat sur son rattachement \u00e0 la Bretagne s&#8217;inscrit dans une histoire ancienne, aliment\u00e9e par des mobilisations associatives, des prises de position d&#8217;\u00e9lus et des discussions sur l&#8217;organisation territoriale.<\/p>\n<p>Modifier les limites d&#8217;une r\u00e9gion rel\u00e8ve d&#8217;une proc\u00e9dure institutionnelle et de d\u00e9cisions publiques, non d&#8217;un sondage.
