The total population figure for the 26 counties is up from 3.14million just over a century ago, in 1911, when it was less than half what it had been in 1841.
In 2016, some 78% of the population - 3.7m people - declared themselves as Roman Catholic, a reduction of more than 130,000 since 2011 when 84% stated they belonged to this church.
Meanwhile, slightly less than half a million people (468,400) declared they had no religion. Now representing 10% of the current population (it was 6% in 2011), this 'no religion' group now makes up the second largest 'religious' category in the Republic.
