The Irish LongituDinal Study on Ageing (TILDA) is a large-scale, nationally representative, longitudinal study on ageing in Ireland, the overarching aim of which is to make Ireland the best place in the world to grow old. TILDA collects information on all aspects of health, economic and social circumstances from people aged 50 and over in a series of data collection waves once every two years. TILDA is unique amongst longitudinal studies in the breadth of physical, mental health and cognitive measures collected. This data, together with the extensive social and economic data, makes TILDA one of the most comprehensive research studies of its kind both in Europe and internationally.

A note on harmonization with the Health and Retirement Study (HRS): TILDA is modeled on the HRS questionnaire allowing for comparability with the HRS and a number of longitudinal studies across the world which have also followed the HRS design. TILDA is currently collaborating with the Gateway to Global Aging Data initiative (G2G) which identifies comparable questions across surveys and has created tools to facilitate cross-country research. TILDA is in the process of generating harmonized versions of its public release datasets to allow for analysis between all studies involved in the harmonization project.
