The dissemination French census results since 2009 INSEE (French NSI) - Demographic departement
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 series • We 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was first paper, then online • for a yearly large dissemination, paper would bee expensive and immediately « outdated » • Even the official popuations are only online • The dissemination of french census is only online • All the products are free for all users
Main points of the strategy (3) • 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
Main points of the strategy (4) • 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

Products for professional users • data that can be reprocessed. • Users sensitive to questions of statistical significance, comparability,changes in concepts : read documentation • Use their own tools for processing and editing. • Two types of products • "bases " : requires knowledge of the functionality of a spreadsheet. (formats, XLS and TXT). • "micro data files" : must be read and processed with software processing database or statistical software.
Bases and microdata • Downloadable bases (hypercubes) makespossible any geographical aggregation of any calculated indicator • Microdata can be used to build user’s own indicator, to study a sub-population, to make modeling behaviour studies… • 8 different microdata files, either with geographical details, either with description or breakdown details, according to CNIL regulation
Conclusions • The schedule was respected • It was a large success for all types of users : rich, easy tu use, well documented • Some users ask for more or easier • Improvement made for the second year …. But • Thise device is expensive : about 1,4 M€ for the construction, 400 000 € each year. • Not integrated in the global Insee Web site.
