A think-tank says an older Irish population will mean 'substantial' increases in demand on the healthcare system.
Projections from the ESRI are based on population growth from the 2016 Census.
It says that between 2015 and 2030, the population is expected to grow by up to 23% - with those over 65 set to increase from one-in-eight to one-in-six.
It also says the numbers of people aged 85 and over are projected to almost double.
The ESRI says demand for health and social care is predicted to increase across all sectors, with the greatest growth for services for older people.
Demand for home help and residential care places in nursing homes is projected to increase by up to 54%, while demand for public hospital services is set to increase by up to 37% for inpatient bed days.
The ESRI says demand for GP visits is also set to grow by up to 27%.
