Multi-exposure environmental scores for the Île-de-France region (indicators reported to intermunicipal authorities)

Environmental exposures are not evenly distributed over the Ile-de-France region and do not affect all categories of the population in a homogeneous manner.This layer of data makes it possible to reveal the situations of cumulative exposures of from a geographical point of view, the result of crossing different environmental data through an environmental score that ranges between 0 and 100. The higher this score, the greater the probability of the occurrence of health effects related to to the environment is high. In order to take into account the greater fragility and less coping capacity of certain population groups (the youngest, the oldest, the chronically ill, the less privileged), the score was combined with two scores considering the characteristics of the population to propose a geography of the accumulations of environmental exposures which integrates the differentiated probabilities of occurrence of health effects (for the same level of exposure, the targeted categories will have a greater risk than the less fragile of them suffer the health consequences). This second score is called the environment and vulnerability score. As part of the PRSE3 Île-de-France, this analysis extends and supplants an initial work to identify environmental black spots carried out in the previous PRSE2 plan. It was carried out by ORS Île-de-France in partnership with the environment department of the Paris Region Institute and Ineris. The calculations and analyzes were carried out with the square unit mesh of 500m side, then synthesized with the intercommunality.
