New figures from the Central Statistics Office show that the enforced deprivation rate increased to 17.8% last year from 15.1% in 2018.
The enforced deprivation rate is defined as not being able to afford two or more deprivation indicators such as keeping your home adequately warm or buying presents for family and friends at least once a year.
The CSO said that most socio-demographic groups experienced an increase in enforced deprivation rates last year.
The biggest increase was seen in those living in rented accommodation, where 34.4% were living in enforced deprivation last year, compared to 27.4% in 2018.
But there was little change in the year-on-year deprivation rate of those living in owner-occupied accommodation, with the rate rising to 10.3% in 2019 from 10% in 2018.
People living in households with one adult and one or more children aged under 18 had the highest enforced deprivation rate in 2019 at 45.4%.
Unemployed individuals (36%) and those individuals who were not at work due to permanent illness or disability (43.3%) also had high enforced deprivation rates in 2019, the CSO said.
Meanwhile, the lowest enforced deprivation rates last year were recorded amongst people who were retired (9.4%), households with three or more persons at work (7.4%), and those with a third level degree or higher (5.3%).
Today's figures show the most common types of deprivation experienced by Irish households last year were an inability to afford to replace worn out furniture (18.1%), to be able to meet family or friends for a drink or a meal once a month (13.6%) or to afford a morning, afternoon or evening out in the last fortnight (11.7%).
