ABOUT THE STUDY

TILDA is a major inter-institutional initiative led by Trinity College Dublin which aims to produce a massive improvement in the quantity and quality of data, research and information relating to older people and ageing in Ireland. 

  • Eligible respondents for this study include individuals aged 50 and over and their spouses or partners of any age.
  • The study will involve interviews on a two yearly basis with a sample cohort of 8,504 people aged 50 and over (or their spouses/partners) and resident in Ireland, collecting detailed information on all aspects of their lives, including the economic (pensions, employment, living standards), health (physical, mental, service needs and usage) and social aspects (contact with friends and kin, formal and informal care, social participation).
  • Both survey interviews and physical and biological measurements are utilised.
  • The study is closely harmonised with leading international research so as to ensure adoption of best practice and comparability of results.

The TILDA project is funded by Irish Life, Atlantic Philanthropies, and the Department of Health. The support of these early funders allowed this project to be conceived, planned, and implemented.
