The population of the state is now the highest it has been since pre famine times, with 5.12 million people living in the country according to the 2022 Census.
The population of Dublin in particular has seen a big increase, growing by 103,342.
There are now over 1,450,701 living in the capital, which is up 7.7% from over 1,347,359 six years ago.
The preliminary figures released by the Irish Central Statistics Office (CSO) show that the the population was 5,123,536 on 3 April.
The population increase of 361,671 was made up of a natural increase (births minus deaths) of 171,338 and estimated net inward migration (population change minus natural increase) of 190,333.
The population across the island of Ireland was devastated by the famine which occurred between 1845 and 1852.
One million people died as a result of the famine and a further two million emigrated.
The Census, normally held every five years, was postponed last year due to the Covid-19 pandemic. Instead, it was carried out on Sunday 3 April.
In the six years between Census 2016 and Census 2022, there was net inward migration of more than 190,000.
The preliminary results published 12 weeks after Census night are based on initial counts from more than 5,000 enumeration areas.
Taoiseach Micheal Martin welcomed the news that Ireland’s population has now passed five million people, “showing the benefits of economic and employment growth in recent years”.
He said: “I also welcome confirmation that the population has increased across every part of the country, with every county in Ireland seeing an increase in their population since 2016, as part of an overall increase of nearly 8% in that time.
“While the number of houses has increased, we clearly need to build more homes as quickly as we can, and the Housing for All plan will ramp-up housing output further in the next few years.
“The census is far more than a simple counting exercise, it gives us the information that is vital for everything from the planning and delivery of public services, to where we need to build housing, to how we arrange our electoral constituencies.”
There were 2,593,600 females and 2,529,936 males recorded in the Census, which is an increase of 7.7% and 7.5% respectively.
