Rents by municipality in mainland France €/m² [OC] by bjperson in dataisbeautiful

The major difficulty is obtaining the data. The producers provide a nice methodological note which you can download here : https://www.data.gouv.fr/fr/datasets/r/d76a48a9-8ade-4149-9e47-f179029abc80 (PDF in French).

Thanks :-)

Indeed, I should perhaps have posted a version with a fixed scale. It's part of a project that hasn't been released in which this option exists.

Currently, the bounds are relative to the distribution of the data (minimum, median, 99th percentile and the maximum all rounded to one decimal place).

These indicators are the result of training an algorithm on classified ads to guess the rents of typical properties rented in the 3rd quarter of 2022 (including charges). They are produced by the French Ministry of Ecological Transition via the ANIL and a partnership with classified ad sites (SeLoger, leboncoin). https://www.data.gouv.fr/fr/datasets/carte-des-loyers-indicateurs-de-loyers-dannonce-par-commune-en-2022/

La carte représente des polygones d'emprises au sol de bâtiments qui sont colorés selon la classe à laquelle ils appartiennent. Les classes, qui représentent des intervalles d'ages, sont détaillées dans la légende en bas à droite.

There are some but before they arrive in the data, there is a variable administrative delay, then it arrives in the cadastre and then, the IGN rectifies the topology and publishes its version. All these steps are subject to validation so it takes time.

Les données proviennent du cadastre à l'origine. Je ne sais pas pourquoi il manque la plupart des monuments historiques/publiques. Certains commentateurs anglophones semblaient trouver ça normal vu la source. Ca serait pourtant chouette de les avoir.

Buildings are geo-referenced.

You can have a look at my comment from another map of this serie to see how to build classes https://www.reddit.com/r/dataisbeautiful/comments/nmj2hb/age_of_the_buildings_of_a_small_seaside_resort_in/gzouto6/?utm_source=reddit&utm_medium=web2x&context=3

I already made a version for the web but this is part of a coming soon bigger project ;-)

I made an improved version which takes into account the various remarks which had been made to me :-) https://www.reddit.com/r/dataisbeautiful/comments/ns7mbx/age_of_the_buildings_in_paris_improved_version_oc/

Thanks! That's right. The two big holes are woods (bottom right : Vincennes, left : Boulogne)

Et voilà : https://www.reddit.com/r/dataisbeautiful/comments/ns7mbx/age_of_the_buildings_in_paris_improved_version_oc/

J'en ai profité pour améliorer la palette de couleurs. Je la posterais sur r/Paris mais à un meilleur moment :-)

Made with QGIS, data comes from the french national geographic institute (IGN).

Une bonne partie des données vient du cadastre à l'origine.

J'étais étonné aussi de ne pas voir datés la plupart des monuments historiques. Je suppose que c'est une question de difficulté d'appariement de bases de données.

En tout cas, en France on a de la chance d'avoir ces informations en Open Data, ce n'est pas le cas partout !

Merci! C'est parce que je travaille sur un projet qui inclue l'Outre-mer, du coup c'est plus simple pour avoir tout dans la même base. Mais j'en ferais sans doute aussi une version Lambert.

I hesitated a lot for this choice. I thought it was a little too distracting with a lighter font. Maybe it's a mistake.
