Ce sont des données de déplacement domicile-travail en 2014 issues du recessement de l'INSEE. **Source des données hackaviz 2019**http://toulouse-dataviz.fr/hackaviz-2019-telechargement-donnees Le nombre d'emplois dans la commune (taille des cercles) est calculé en additionnant tous les déplacements à l'interieur de la commune (inter) et ceux entrants dans la commune **MAIS** ne sont comptés que les flux entrants qui sont supérieurs à 100 (obtenus à partir de flux de commune à commune de l'INSEE : Flux_dom_travail_BTX_FM_DTR_2014.csv). Il exite un autre fichier insee qui recense pour chaque commune le nombre de personnes qui travaillent en dehors de la commune. ce nombre comptabilise tous les flux. Exemple à Millau 1788 personnes travaillent en dehors de la commune et seulement 1134 si on comptabilise que le flux >100. pour Saint-Afrique on a 1009 contre 424. Nous n'avons pas accès à la valeur de toutes les personnes venant travailler dans la commune sachant qu'en dessous de 100 les flux ne sont pas fiables dexit l'INSEE. Dans les calculs on considère que tous les flux <100 sont égales à zéro ce qui permet d'avoir une estimation moins imprécise sur le différentiel entrant - sortant et sur le nombre d'emploi dans la commune. millau - extra 1788 tous flux sortant confondus - extra 1134 tous les flux sortant > 100 - inter 6419 - intra 1420 tous les flux entrant >100 6419+1788 = 7553 6419+1134 = 8207 L'erreur sur le nombre d'emploi est faible et pas significative dans le cadre de cette dataviz. Dans le cas ou l'ecart entre le nombre sortant / entrant est faible , la couleur peut être erronée notamment pour les communes les moins peuplées. Les données sirene semble donner des résultats très inférieurs à ceux des flux. Tous les emplois ne sont pas comptabilisés dans la base Sirene Si un flux arrive sur une commune dont le cercle n'est pas coloré, cela indique qu'il n'y a aucun flux sortant identifié pour cette commune INTER : Travail à l'interieur de la commune EXTRA : travail à l'exterieur de la commune INTRA : travail depuis l'exterieur vers la commune
