General description
Surveys
Seven major surveys will be carried out during the lifespan of this project. Four of these are national surveys and the remaining three are European surveys. In addition to these surveys, LifeObs will facilitate the use of other data, such as the EDP (Échantillon démographique permanent / Permanent demographic sample) and TCM (Tronc commun des ménages / Common household questionnaire).
- National surveys
  4 french surveys
- European surveys
  3 european surveys
- Others data : TCM et EDP
  The LifeObs project will promote and facilitate the re-use of other databases, such as the EDP (Échantillon démographique permanent / Permanent demographic sample) and TCM (Tronc commun des ménages / Common household questionnaire).
  - TCM (tronc commun des ménages) Common household questionnaire
  - EDP (échantillon démographique permanent) Permanent demographic sample
Methods
The eight surveys of the LifeObs project will be coupled with methodological innovations regarding the preparation of longitudinal surveys, multi-mode data collection, the use of new software, and the enrichment of surveys via matching with various administrative data sources.

Survey methodology

The role of the Innovation Department is to bring together information and foster discussions on innovative methods to be developed and used by the project’s surveys. As such, this department will support the teams in charge of producing the surveys, particularly when they face methodological challenges; most notably, the department will solicit experts who can help overcome the confronted challenges.

In general, the department will focus on the following topics: multi-mode surveys (methods for collecting data and for analysing and exploiting surveys collected using different data collection modes, sequentially or concurrently), longitudinal surveys (managing panels and re-interrogations, accounting for attrition and adjustments), matching of survey data with administrative data (expertise in administrative data, in particular, tax data and data from large statistical studies)[1] , matching techniques and the facilitation of access to data, software for developing and producing questionnaires, and work concerning financial incentives.

Depending on the needs of the project, the department will also organise meetings on a selection of these topics; the meetings will be developed in line with the work processes and working patterns that will be established as the project progresses.
