Data on Priority A new method to protect statistical confidentiality
Updating the geography of priority urban policy Data on Priority districts (QPV) in 2024 raises a difficulty for INSEE : disseminate statistical information relating to old and new QPVs? while protecting statistical confidentiality. The proximity between the contours of the old and new districts can indeed lead to risks of breach of confidentiality by “Data on Priority geographic differentiation” in certain areas.
The traditional solution of “hiding
boxes in the disseminated data files is reaching its morocco phone number library limits: it leads to deleting a very large number of boxes and the loss of information is too significant.
In order to overcome these limits? INSEE is now using a new confidentiality management method? called “random keys” ( cell key method ). Instead of hiding boxes? this method consists of slightly “noising” the original data with a random disturbance? which must be both sufficient to guarantee confidentiality and not too great to minimize the loss of information.
In order to inform the public debate on urban policy? INSEE regularly publishes statistical data files on Priority Neighborhoods of Urban Policy (QPV)? which allow interested stakeholders to study the characteristics of the populations living in these neighborhoods. These include demographic estimates based on the population census? indicators of standard of living and smartphone life statistics how long inequalities or the number of job seekers. Before publication? these data files are processed in order to protect statistical confidentiality? i.e. to make it impossible to identify and disclose the situation of a particular person from the data disseminated.
The priority geography has been updated
The outlines of the QPVs in metropolitan aero leads France were revised on 1 January 2024 in order to take into account the demographic and economic developments in the territories since the implementation of the QPVs in 2015. This operation? carried out by the National Agency for Territorial Cohesion and the departmental prefectures? was based on data from the INSEE Local Social and Fiscal File (Filosofi). INSEE proposed a statistical portrait of these new QPVs in August 2024.
