The Irish LongituDinal Study on Ageing (TILDA) is the most detailed study on ageing ever undertaken in Ireland and it is made possible by the generosity of all our participants, who have given up their time to speak to our interviewers, fill out questionnaires and undergo health assessments.

This ground-breaking study looks at the health, lifestyles and financial situation of 8,504 people as they grow older, and sees how their circumstances change over a 10 year period. The study is being carried out by Trinity College Dublin in collaboration with an inter-disciplinary panel of experts in various fields of ageing.

The information gathered by TILDA improves our understanding of the factors that aid successful ageing in Ireland. It also assists in the development of a range of economic, health and social policies benefiting all people living in Ireland. Some of the questions we are interested in answering are:

  • What are the factors that determine successful ageing?
  • How do people’s health and level of disability change over time?
  • What happens to people’s memory as they age?
  • What are the causes of memory changes?
  • What are the factors that decide when people retire and how do people plan for their retirement?
  • Do people have enough savings to provide for their older age?
  • How can we help people understand the economic requirements of ageing?
  • How do people’s activities, relationships and quality of life change over time?
  • What is the relationship between people’s health status, economic situation and social circumstances?
  • How does this relationship change over time?
  • How can we use these relationships to improve quality of life in ageing?
