Irish Longitudinal Study on Ageing
The principal objective of the Irish Longitudinal Study on Ageing are to determine:
- the health status and health needs of older people
- the social and economic status and needs of older people
- the health, economic and social needs of families and carers of older people
- the biological and environmental components of "successful ageing"
- the contributions that older people are making to society and the economy
- how each of these key components (health, wealth, happiness) interact such that we can ensure that Ireland meets the needs and choices of its citizens in a personalised and positive environment and with due dignity and respect

Timeline
Population
Eligible respondents for this study include individuals aged 50 and over and their spouses or partners of any age.
A nationally representative sample of at least 8,000 adults aged 50 and over, resident in Ireland, was selected using a population sift. The selected addresses were visited by an interviewer from Ipsos MORI and all persons aged 50 or over (and their spouses/partners of any age) were canvassed to participate in the survey. 8,504 participants were recruited to the study. These include 8,175 respondents aged 50+ and 329 younger partners of eligible individuals. The household response rate to the study was 62%.
