Direct download service (WFS) of the dataset: Indicators of “potential fragility” of flag areas post 1950

The Priority Pavilion Areas Study aimed to identify the “most fragile” pavilion areas according to a number of criteria chosen to represent different areas of potential fragility that these neighbourhoods might experience in the future: economic weakening of households, ageing of the population, ageing and inefficiency of housing, value of real estate, difficulties in geographical accessibility to jobs, businesses and public or private services, overconsumption of energy, natural hazards... All the lodge areas have been identified, cut and analysed according to the geographical prism of INSEE’s “carroyed data” (2010), which provide some anonymised statistical data per 200 m per 200 m side, to which we have added other sources of geolocated data, calculated or evaluated on the same area: real estate, equipment, transport, consumption... A tile has been defined as “pavillonnaire” if it includes: more than 50 % of individual housing and a density of more than 250 inhabitants per km² (in order to differentiate them from scattered habitats related to agricultural activities). A total of 9 indicators have been calculated, and thresholds of “most unfavourable quarters” – among all the flag areas in the region – have been determined in these different sets of indicators. Only the carroyed areas included in these unfavourable quartiles have been identified as “potentially fragile” on each of the criteria analysed, in the manner of data on “poverty thresholds”, for example. Such a “quartile” threshold remains quite arbitrary, but aims to highlight areas with the most potential difficulties to come. Thus, 9 “potential fragility criteria” were constructed, for each flagging “tile” of 200 by 200 m, based on the following data and thresholds of unfavourable quartiles (figures on the right): Criterion A = “Economically unfavourable” = Low-income household rate | quartile threshold ≥ 20.00 % Criterion B = “Vieillating” = Rate over 75 | Quartile threshold ≥ 11.11 % Criterion C = “Extra from large equipment” = High school ≥ 9.52 km + Supermarket ≥ 5.41 km + Hospital ≥ 11.31 km (Threatest quartile growth on these three indicators) Criterion D = “Low real estate value” = price ≤ EUR 1434 per m² Criterion E = “monofunctionality” = Pavilion area of more than 40 contiguous hectares (10 tiles) Criterion F = “Risk and nuisance” = Pavilion area built mostly on a PPRT or PPRI area Criterion G = “Forte energy consumption” = combined indicator of energy habitat and displacement estimated according to a mathematical model developed by ELIOTH, with the most unfavourable quartile used as the threshold Criterion H = “Low access to transport” = No public transport within a radius of 400 m Criterion I = “Lack of connectivity” = Area outside very high speed deployment
