TILDA collects information on all aspects of health, economic and social circumstances from adults aged 50 years and over resident in Ireland. Waves of data collection take place every two years. TILDA provides a comprehensive and accurate picture of the characteristics, needs and contributions of older persons in Ireland to inform and support improvements in policy and practice; advancements in technology and innovation; tailored education and training through an enhanced ageing research infrastructure; harmonisation with leading international research to ensure adoption of best policy and practice and comparability of results. TILDA is necessary to act as the foundation on which we can plan appropriate health, medical, social and economic policies for our older adults. Harmonised TILDA is a internationally comparable version of the TILDA data developed in conjunction with Gateway to Global Aging Data (G2G). It is a single datafile which contains waves 1 and 2 of TILDA with variables formatted according the G2G data convention to enable cross-country analysis. The harmonised dataset is currently available in STATA, SPSS and SAS formats. Full metadata and codebooks are available through the G2G website.
