Situation 2017-2020 Environmental exposures are not uniformly distributed across the Ile-de-France region and do not affect all population categories evenly. This data layer makes it possible to reveal cumulative exposure situations from a geographical point of view, the result of a cross-referencing of different environmental data through an environmental score which ranges between 0 and 100. More this score is higher, the higher the probability of occurrence of health effects linked to the environment. In order to take into account the greater fragility and poorer ability to cope of certain population groups (the youngest, the oldest, the chronically ill, the least advantaged), the score was combined with two scores considering the characteristics of the population to propose a geography of cumulative 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 vulnerable of suffering the health consequences). This second score is called the environment and vulnerability score. Part of the PRSE3 Île-de-France, this analysis extends and replaces 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 unit mesh used is a square mesh of 500m side.Consult the metadata
