This proposal includes all tasks that are essential to maintain the European added value of the Survey of Health, Ageing and Retirement in Europe (SHARE) and to keep the 16 national surveys well integrated. It complements the national financing mode of data collection as result of the ESFRI process by keeping its centrifugal forces in bounds. It will keep up our excellence in service provision as well as in science by:1. Fostering the culture of cooperation between designers and users of SHARE by organizing user conferences, offering specialized training courses for users and interviewers, expanding web services and developing standards and procedures within the network that will make more efficient use of the research infrastructure.2. Improving the multinational services for users in EU member countries, associated countries and third countries by a more efficient centralized data base management that will provide detailed synopses and concordances across member countries. We will coordinate this work with our sister surveys in the UK, US, China, India, Japan, Korea and Thailand, thereby providing a platform for global access to ageing data.3. Pushing the state-of-the-art in interdisciplinary panel construction further such that SHARE will maintain its status as a leading edge research infrastructure. The project will leverage our research on response behaviour to minimize attrition; it will develop a multi-mode interviweing facility tailored to the 50+ in order to reduce survey costs; it will develop innovative questionnaire modules on biomarkers, physical health, social networks, pension claims, time use and nutrition that will keep SHARE at the forefront of empirical science; and, with the help of EUROMOD, it will harmonizes income concepts across EU-surveys, notably EU-SILC in order to facilitate the measurement of material well-being in times of rapid demographic change with its complex implications for old-age income provision.
