A report by the Central Statistics Office on Health, Disability and Carers has found that 87% of the country's population felt they were in good or very good health, slightly down on the Census five years earlier.
The highest percentage of people feeling healthy was in Dún Laoghaire Rathdown, where nine out of ten people said they were in good or very good health.
Those feeling less healthy could be found in Dublin and Cork cities.
The report also looked at the country's 195,000 carers who provide over six-and-a-half million hours of unpaid care every week.
It found 60% of them are women, and that most are middle-aged.
It also found that 3,800 carers are under the age of 15.
The number of people reporting a disability is up by almost 48,000 - with the largest increase amongst those reporting a psychological or emotional condition - this grew by over 28% in five years.
Eileen Murphy, a statistician with the CSO, said today's figures show an increase of people living with a disability in Ireland.
Speaking on RTÉ's Drivetime, she said all the different categories of disability showed an increase in numbers, but the largest increase was those with a psychological or emotional condition, rising by nearly 29% to 123,000 people.
Ms Murphy said education attainment amongst those with a disability is much lower than that of the general population of all ages.
"We had over 176,000 persons with a disability in the labour force, giving a participation rate of 30%, but again that's half the population overall of 61%, and then at work we just had a 130,000 people with a disability at work, so that was a rate of 6.5%," she said.
