Elles permettent d’appréhender une institution à travers ses multiples facettes que ce soient ses missions, son fonctionnement, son organisation ou ses accomplissements. L’EPFL se dévoile ainsi à travers ses données et les chiffres qui la définissent, révélant des statistiques générales tout comme des aspects parfois inconnus. Pour l’EPFL, la transparence de ses données est aussi un outil de communication pour refléter son identité, son évolution et son dynamisme.</p><p>Ce site vous présente les données institutionnelles de l’EPFL. Vous y trouverez les données brutes des principaux indicateurs de l’École et vous pourrez explorer leur évolution. Vous trouverez également des mises en perspective thématiques reflétant les actions de l’EPFL dans des domaines clés, ainsi que l’impact d’une institution académique sur son environnement et son rôle au sein de la société.</p></div></div></div></div></div> <div class="container-full py-3 p-lg-5 bg-gray-100 py-4 my-4"><div class="container"> <div class="card-deck "><div class="card"> <a
