Geographic scales impacts on segregation index

Aurélien Dasre, Université Montesquieu Bordeaux IV

All segregations studies have to do 3 choices: the area of the study, the geographic subdivision of the area and the populations that you will follow Based on a microsimulation pattern, this paper will demonstrate that a same segregation index, calculate at two different geographical subdivision scale can provide two different results. If it’s well known that the index will be higher with finest geographical scale, we will also demonstrate the mathematical relationship between these results. Apply to the French biggest city area; this paper will show that comparing these different values in function of the geographical scale can bring valuable information’s on segregation phenomenon. We would like to show that if it’s important to study segregation among the well known 5 dimensions, compare index calculate with different geographical scale should be considerate in any study of this type.
