What comes to mind is typically bleak pictures of overcrowding, crumbling infrastructures and bad quality of life. Yet it can correspond to strikingly different realities. It is not only endless patches of decaying housing projects but also affluent neighborhoods!<\/p>\n\n\n\n<p>I have recently stumbled upon the work of Alasdair Rae, a British analyst who produced beautiful maps of <a href=\"http:\/\/www.statsmapsnpix.com\/2023\/02\/the-most-densely-populated-square-km-in.html\" target=\"_blank\" rel=\"noopener\" title=\"\">the areas with the highest densities in each US State<\/a>. I thus carry on my &#8220;tradition&#8221; of stealing original ideas from the Anglosphere (see <a href=\"https:\/\/dismalscience.eu\/?p=735\" title=\"Where are the French sinners?\">here<\/a>) to generate new articles (I am currently working on a large-scale, 100% original project, but it will still have to wait&#8230; keep posted). <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Soporific tax data can be (somewhat) exciting!<\/h2>\n\n\n\n<p>This article does not have very strong analytical ambitions. I would rather present a snapshot of what density <em>actually <\/em>looks like today in France. To answer this simple question, I rely on the new <a href=\"https:\/\/www.insee.fr\/fr\/metadonnees\/source\/serie\/s1172\" target=\"_blank\" rel=\"noopener\" title=\"FILOSOFI\">FILOSOFI<\/a> dataset from INSEE. This dataset &#8220;cuts&#8221; the French territory into &#8220;grids&#8221;, which are essentially squares with granular geographical information (for instance for tax-related issues). The dataset also contains information on the population of these grids. I thus take the 1 km x 1 km squares and take a look at their density across France. <em>(There are lots of complex and boring technicalities I skip here, but obviously the results would depend on how you define the squares &#8211; and as you will see there are some strange results). <\/em><\/p>\n\n\n\n<p>If we look at the distribution of the densities of these grids, we obtain this: (note the scale is logarithmic!) <\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/popdensity-1024x733.png\" alt=\"\" class=\"wp-image-849\" width=\"768\" height=\"550\" srcset=\"https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/popdensity-1024x733.png 1024w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/popdensity-300x215.png 300w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/popdensity-768x550.png 768w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/popdensity-600x430.png 600w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/popdensity.png 1394w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><figcaption class=\"wp-element-caption\">Source: FILOSOFI (INSEE)<\/figcaption><\/figure>\n<\/div>\n\n\n<p>Without any surprise, the neighborhood with the highest density of the country is located in Paris (it is a part of the 18th <em>arrondissement<\/em>). But what does it look like on the ground (or more accurately, from a bird&#8217;s eye view)?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Turning everything into maps<\/h2>\n\n\n\n<p>Here I rely on data from the <a href=\"https:\/\/www.geoportail.gouv.fr\/\" target=\"_blank\" rel=\"noopener\" title=\"GN\/Geoportail\">IGN\/Geoportail<\/a>, which allows the extraction of detailed aerial maps of the French territory. So here is the famous tract of land with the highest density in France:<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/75-1024x1024.png\" alt=\"\" class=\"wp-image-827\" width=\"512\" height=\"512\" srcset=\"https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/75-1024x1024.png 1024w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/75-300x300.png 300w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/75-150x150.png 150w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/75-768x768.png 768w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/75-1536x1536.png 1536w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/75-2048x2048.png 2048w, https:\/\/dismalscience.eu\/wp-content\/uploads\/2023\/02\/75-600x600.png 600w\" sizes=\"auto, (max-width: 512px) 100vw, 512px\" \/><\/figure>\n<\/div>\n\n\n<p>Quite packed!
