There were up to 2,300 excess deaths between March 2020 and February 2021 compared to previous years, according to an analysis of death notices by the Central Statistics Office.
Researchers examined 30,000 death notices on the RIP.ie website over that period with the data showing a range of estimates for excess deaths between 2,034 and 2,338.
The first reported death due to Covid-19 in Ireland was on 11 March, 2020. Excess mortality measures the number of deaths over and above what would be expected under normal circumstances.
In figures released this morning, the CSO said there were pronounced increases in the number of death notices observed in April 2020 and in January and February 2021 compared to the same months in 2017, 2018 and 2019.
