The Life Expectancy of a Child Born in Ireland in the Twenty-First Century

Period Life expectancies for the Irish population are projected and published by the Central Statistics Office (CSO) and the United Nations (UN). This article estimates cohort life expectancies at birth in Ireland over the remainder of the 21st century together with 80% and 95% prediction intervals consistent with these official estimates. We report that a female born in Ireland in calendar year 2020 can be expected to live to 92.6 years with a 95% prediction interval around this estimate of 86.8 years to 97.3 years. For males born in 2020, the central estimate is 90 years with 95% prediction interval of 83.9 years to 95.2 years. The probability that cohort life expectancies at birth will reach 100 years before the calendar year 2100 is less than 10% for females and less than 2.5% for males.
