Older men in Ireland are much more likely to have a living partner than women, who have a higher risk of being widowed.
Among the over-65s, up to 39.8pc of women are widowed compared with 12.7pc of men.
The difference is due to Irish women living longer.
At 65 a woman can expect to live at least 20 years more while for men it is 17.4 years.
The countries with highest life expectancy for women are France and Spain – which has the longest living men.
The Long-Stay Activity report also reveals that two-thirds of long-stay nursing home residents are female.
Scientists believe that oestrogen in women combats conditions such as heart disease by helping reduce harmful cholesterol.
Women are thought to have stronger immune systems. They pay more visits to GPs, meaning ailments are likely to be picked up earlier.
