Index of distance from high schools

The distance from high schools can be described statistically continuously using a synthetic indicator that takes into account, for a given school, multiple dimensions: the place of residence of the pupils he/she attends, the educational offer and the surrounding facilities. The ‘remoteness’ index makes it possible to summarise the concept of remoteness for a given institution in an indicator. It makes it possible to: \- to take into account the different aspects of rurality and remoteness of settlements \- to classify all establishments on an ongoing basis, from least "remote" to most "remote" and thus provide a relative approach. All the academies, even the most urban ones such as those in Île-de-France, have relatively ‘remote’ establishments; Intuitively, a first possibility to describe in a continuous way the rural character of an establishment would be to retain, for each secondary school, the proportion of its pupils who reside in a rural municipality. This proportion varies from 0 to 100%. However, it has a double disadvantage. On the one hand, it does not distinguish between the different forms of rurality, from the remote, very sparsely populated rural to the peripheral, sparsely populated rural. On the other hand, its one-dimensional nature obscures the variety of forms that may be taken by the removal of establishments: an establishment may be in a remote situation even in urban areas. Therefore, the approach must take into account several dimensions that relate to the concept of distance for a school and its pupils. For a given high school, three types of variables are distinguished: \- Variables for students attending this school \ - Variables relating to school or higher education provision around the institution \ - Variables relating to the cultural and infrastructural offer around the establishment It was decided to set the median of the index at 100, which means that the value of the index is less than 100 for half of the least distant high schools and more than 100 for the most distant half. The higher the value, the greater the distance.
