INSEE (French NSI) - Demographic departement

The dissemination of French census since 2009 Geneva July 2010

- Since decembre 2008, the « official populations » of the 40 000 administrative units are calculed and disseminated by Insee, yearly

- Since july 2009, all the detailled statistical results of census are also disseminated, yearly.

- This presentation describes the device decided by insee for this dissemination

- 1. The strategy- 2. The products- 3. Points of assesment


I - Main points of the strategy (1)

›A. All results updated every year ?›Why ?

–It is possible with the new method, using 5 surveys

–Users ask for « the latest » information at every moment

– concistancy with official population figures›Why not ?

– It is expensive– Data of successive dates do not constitute actual

yearly seriesWe decided to do it


Main points of the strategy (2)

›B – Paper or online ?– the former dissemination was first paper, then

online– for a yearly large dissemination, paper would

bee expensive and immediately « outdated »–Even the official popuations are only online

The dissemination of french census is only onlineAll the products are free for all users



›C – What want the users ? What about confidentiality ?– Users were consulted trough the CNIS

• they wanted to find all what they had with the « old » census

• with documentation, because of the new method– The proposition of device was presented to the

CNIL, and a « dissemination regulation » was edicted‐ different size of the tables for different population of territories‐ micro data bases wtih either geographical precision, either breakdown detail

‐ A little number of « sensitive » variables with specific rules



›C – How can we help the users ? Make them independant.– the conception of the website– a large documentation– a specific « supporting » for some specific users, by regional Insee teams.






II – Different products for different audiences›Two main categories of users :›General public, including policymakers, media : immediately avaible on screen, without specific precautions›Professional users (public organizations, local

authorities, large companies, consultants, research...).: build information independently, by exploiting online available databases.


Three products for general public

›Key figures :• For all geographical areas, even very little• online and PDF• Tables and some simple graphics• Comparaisons with 1999 census

›Detailled tables •for areas of more than 2 000 inhabitants•online and XLS•Only effectif tables•No comparaisons on the website

› Dynamic Maps
