Introduction
The main goal of this study is to understand how spatial socio-economic features of the Vernier municipality are developed through the geographical space by looking at polluted areas. This paper is part from a bigger study, which has the main goal to determine a vulnerability index for population. This index takes into account many economical features (as the revenue per household, unemployment rate, diversity of jobs), environmental characteristics (as the richness of green spaces, their locations, distance of populations from polluted soil areas), wealth indicators, and safety aspects. We take the municipality of Vernier as our reference in order to build up our index, so we will be able to extend the application of this index to other cities. We will focus our study for the moment by looking at the distribution of population through the geographical space, and try to explain this spatial arrangement by looking at polluted areas. The main goal here is to provide a map in order to give some basic features of the municipality of Vernier in order to guide the work for the overall study. We hypothesize that districts containing polluted areas are less attractive, hence are cheaper. As a results, we tend to think that citizens having less revenue live in these districts. We will look at some basic socio-economy features (as revenue per household, unemployment rate) which are known to be good translators of the corresponding social class, as well as polluted area in the municipality of Vernier. We will try to verify this hypothesis in the following paper.
