Inflation in Ireland hit 7.8% in May.
It's the biggest annual increase since 1984.
Estimated figures from Eurostat late last month had prices increasing by 8.2% in May.
The rate has now been confirmed by the CSO to be at 7.8%.
In May, the largest increases were seen in housing, energy costs and transport.
Alcohol and tobacco saw rises of 2%, while restaurants and hotels only saw prices increase by just over 1%.
Meanwhile, the CSO also released figures on household savings, which shows on average 19% of paychecks are being put away for a rainy day.
It's double the rate of saving in 2019.
