Being a part of the Y generation, I grew up listening to various types and genres of music, from Rap to RnB, to Rock and electronic music. I was personally choked to hear about the death of the lead singer of the Linkin Park band. Their music was and still is popular until today. The news was as choking to me as to anyone else who knew that band. After knowing about the news, I had a discussion about this tragedy , and a question popped up about the fact that rock band members mostly die of suicide or drug over-dose. I wasn't really sure that this information is true, so I really couldn't have a real argument to say that it is maybe (or not ) the most commun reason of death for Rock stars. And since I love playing with data, I decided to fact-check the hypothesis stating that:  "The most commun cause of death among rock band members is suicide" . To start, we have to get  some data! and since there is no available data-set to analyse , I had to be creativ...

Introduction la Tunisie vivait une situation économique très difficile depuis une période de 5 ans,  chaque fois qu’on croit toucher le fond, les choses empirent davantage. Un dinar en chute libre, des exportations en recul et des investissements qui n'avancent plus : c'est le constat global établi depuis 2011. Nous allons essayer dans cet article de détailler quelques chiffres clés afin de donner une image plus consistante et plus claire sur l’état des lieux de l'économie Tunisienne.

La Tunisie avait toujours le label du "petit" pays, avec peu de ressources et de moyens. Ce label était une sorte d'excuse ou d'argument pour justifier la lenteur du développement du pays et les difficultés rencontrées lors de la mise en place des programmes d'amélioration dans tous les secteurs. Mais ce n'est pas VRAI, la Tunisie n'est pas un petit pays, sa superficie est supérieure à ces pays : Autriche, Émirats arabes unis, Irlande ,Denmark, Pays-Bas, Suisse, Kuwait.. Nous avons plus de ressources humaines que ces pays: Belgique, Autriche, Suisse,Émirats arabes unis, Finlande,Norvège,Luxembourg..
