Dublin's population is continuing to mushroom at a faster rate than anywhere else in the country.
Fingal has become the fastest growing area in the country and also boasts the youngest population, according to Census 2016.
The average age in Fingal county now stands at 34.3 years - in contrast to the national average of 37.4.
Fingal grew by eight per cent in the five years since the last census - more than twice that of the state overall.
Meath in the commuter belt came closest at 5.9pc, while Dun Laoghaire-Rathdown grew at 5.7pc, with Dublin city and South Dublin both expanding by 5.1pc.
Only Cork city, at 5.4pc, came anywhere close to the growth rate of the capital. Nine other counties grew at a rate of less than 2 per cent, with Donegal and Mayo showing a fall in population.
Overall, Leinster accounted for 55.3pc of the national population in 2016, compared with 54.6pc in 2011. In all, there were 62,552 more people living in Dublin in 2016 than five years previously - up from 1,110,627 in 2011 to 1,173,179 in 2016.
However, the census pointed to the growing urbanisation in other counties, with Cork showing an increase of over 10,000 people, with more modest increases in Limerick, Galway and Waterford cities.
The results showed an increase of 48,269 people living in the largest towns in the country.
The census revealed that Dublin's share of the urban population has actually declined in the past 50 years, at the expense of the large towns. In 1966, Dublin had 51pc of the urban population in the country while in 2016, it had just 39pc.
When it comes to the gender breakdown, Dublin city had 96 men for every 100 women, while the lowest in the country is Dun Laoghaire-Rathdown and also Galway city, which both stand at just 92 men per every 100 women.
Dublin city did not top the table for marital breakdown - with Cork city and Galway city showing a marginally higher rate, at 11.9pc and 11.8pc respectively, while Dublin's marital breakdown rate stands at 11.7pc.
The capital showed a lower number of children per family, compared to the rest of the country, with an average of just 1.17 children per family in Dublin city as against the national average of 1.38 children.
Meath showed the higher number of children in the country, with an average of 1.51, followed by Monaghan at 1.50 and Laois at 1.49.
Overall, the Census results showed the population of Ireland has risen in the past five years, edging closer towards the five million mark for the first time since the foundation of the state. In April 2016 it stood at 4,761,865 which is an increase of 173,613 since April 2011.
The total number of non-Irish nationals fell slightly to 535,475 or 11.6pc of the population - the first decline since the introduction of this question in 2002.
This could be explained in part by the rise in number of people with dual-Irish nationality - increasing by 48,879 to 104,784 since April 2011.
The number of Irish residents born outside Ireland continues to increase, standing at 810, 406 in 2016.
