SHARE: Preparatory work for the upcoming Wave 11 continued. In addition to the partial revision of the questionnaire content already mentioned, the change in the delivery medium (from laptop to tablet) is currently being developed, with challenges in terms of delivery time and ergonomics. The main data collection, including a refresh campaign and a drop-off, is scheduled for spring and summer 2027, with a target of 3,500 interviews, i.e. 5 to 10% more than in wave 10. Discussions are underway on the possibilities of matching SHARE with administrative data, following recommendations from supervisory authorities and funders in this regard. The exploitation of data from previous waves is continuing. The SHARE-France team contributed to a treatise on gerontology (Levy & Jusot) and published an article on the impact of disability on the incomes of older employees (Bondoux et al.).
ERFI2 -GGP: Those who agreed to be contacted again for the second wave received a new mailing in September with the initial results. The survey was the subject of an issue of Populations et Sociétés entitled ‘People in France want fewer children’, published in July, which received over 300 press mentions. The agreement with INSEE, CASD and DGFIP concerning the matching of survey data with tax and employment databases (common to the ERFI2 and FamEmp surveys) was signed at the end of August. Preparations for the collection of wave 2 data have begun. Analysis of the survey results is continuing. The operating group has the final weightings and a volume of initial results is being prepared.
GUIDE: The GUIDE Partners Forum was held in September 2025, with all partners in attendance. The Central Hub submitted a GUIDEPREP-2 funding application to the European Union to cover operations relating to the final phase of preparation for the survey of 8-year-old children. In France, Guide received a favourable opinion from the CNIS. The scientific council of Progedo, a research infrastructure bringing together major international surveys, approved the integration of GUIDE into Progedo. The GUIDE survey has received approval from INSEE to draw the sample for the first wave of the cohort of 8-year-old children from the FIDÉLI database. The Guide-INED scientific team presented the survey at the Elfe and Epipage 2 scientific conference in October 2025.
Envie: The survey continues to be promoted. A bulletin on sex education was published in Injep analyses & synthèses, entitled ‘Peers and professionals, young people’s primary sources of information on sexuality’. The collective work, published in the spring, was the subject of scientific presentations at universities in France and abroad, and several conferences for the general public were organised in various cities in France. The research team is continuing its work, both individually and collectively, and the first in-depth scientific articles are currently being published. The team has also grown, notably with the arrival of young researchers: three new theses and a postdoctoral project based on the survey began in autumn 2025. The research team is also involved in producing content for EVARS (education on emotional and relational life and sexuality) teaching based on the survey results and as part of the partnership between INED and DGESCO.
FamEmp: An issue of Populations et Sociétés entitled ‘Work-life balance: who faces the most difficulties?’ was published in October. It presents the initial findings of the individual component on the family and professional configurations most frequently associated with tensions in the balance between work and private life, and the links with health and intentions regarding fertility and professional mobility. The work of the exploitation group is continuing, with the publication of the first results scheduled for 2026. A new newsletter was sent to respondents in wave 1, with results and a questionnaire enabling them to update their contact details. After the data had been cleaned and the weights calculated, the data from the Employers section was made available to the exploitation group in July. La Voix du Client has been selected to conduct the collection of wave 2 of the individual section. The pilot will take place in spring 2026 (the questionnaire is currently being programmed by the polling institute) and the actual survey is scheduled for 2027.
Fertility and reproductive health in overseas territories: The team conducted initial analyses based on interviews and focus groups (Martinique, French Guiana and Réunion) with the target population. The questionnaire design group (G-Co) and the 11 groups responsible for the question modules met between July and November to develop a first draft of the questionnaire, which was tested in December 2025 in Martinique and then in early 2026 in the three other departments. An initial meeting of the Steering Committee was held in November with the ARS and local perinatal networks. We are delighted to confirm that the survey has been included in the regional INSEE collection calendar for the DROMs, with experienced interviewers, who are essential for conducting these surveys! The project was presented to the ANR on 10 December 2025 to outline the administrative and budgetary aspects, as well as the scientific aspects. The presentation was rich in discussions and recommendations.
Families: This period saw the completion of data collection for the Families survey. The final phase of data collection, involving telephone follow-ups with a sub-sample of non-respondents to the online survey, was completed in mid-July, and the digitised data from the paper survey was received at the end of the summer. Downstream work was thus able to begin with the matching of the census and the creation of a single consolidated file, with a view to setting up an exploitation group in early 2027. The prerequisites for carrying out the 13 selected qualitative post-survey projects (legal procedures, sampling and delivery of samples) were completed.
