31 31st July 2017 General
Home News Census 2016 Results: Profile 4 – Households and Families

Number of families increases by 12,729 in Dublin

On the 27th July, The Central Statistics Office published Profile 4 Households and Families, the latest of the eleven Census 2016 profile reports. The report shows that there were 1,218,370 families in the State on Census Night, an increase of 3.3% since 2011. The number of children per family remained unchanged at 1.38 children since the 2011 census.

Deirdre Cullen, Senior Statistician: “This profile report on Households and Families examines the family situations and living arrangements of the Irish population in April 2016. It provides a wealth of information and analysis on topics such as marital status, same sex civil partnerships and the different types and sizes of family composition and households”.

Dublin highlights from Profile 4 Households and Families


Census 2016 recorded 332,592 families in County Dublin, an increase of 12,729 (4.0%) on the 2011 figure.


In April 2016, 46.0% of those aged 15 and over living in the county were single (500,654 people), while just 41.1% were in the State overall. A further 454,912 people (41.8%) were (first-time) married, compared to 46.0% nationally.

There were 16,977 remarried persons in the county. Males were much more likely to remarry after divorce, with 45.7% doing so, compared to just 28.7% of females.

The number of divorcees increased by 3,913 to 29,370, and accounted for 2.7% of those aged 15 and over. The 51,388 widowed persons comprised 4.7% of those aged above 15 years.

Same-sex civil partnerships

Census 2016 marked the first time that this relationship category was recorded in an Irish census, following the enactment of civil partnership legislation. There were 2,176 people in this category in County Dublin, and 4,226 in the State overall.

Living Alone

The number of people living alone in the county fell by 4,398 to 108,409, i.e. 8.3% of all those living in private households. Of these, 40,271 were aged 65 and over, with women accounting for 67.7%.

A summary of some of the headline results from Census 2016 for County Dublin, together with comparisons for Leinster and the State as a whole are attached for information.

  • The full report is available on the CSO website at along with all the data which is available in a range of interactive web tables, allowing users to build their own tables by selecting the data they are interested in and downloading them in an easy to use format for their own analysis.
  • In co-operation with the All Ireland Research Observatory (AIRO) at NUI Maynooth, summary census data is available in thematic maps for Electoral Districts and all Small Areas on the AIRO website. This can be accessed via the link on the CSO website.
  • The census figures relate to the de facto population, i.e. the population recorded for each area represents the total of all persons present within its boundaries on the night of Sunday, 24 April 2016, together with all persons who arrived in that area on the morning of Monday, 25 April 2016, not having been enumerated elsewhere. Persons on board ships in port are included with the population of adjacent areas. The figures, therefore, include visitors present on Census Night as well as those in residence, while usual residents temporarily absent from the area are excluded.
  • The de facto measure of the population in April 2016 was 4,761,865 while the usually resident total was 4,689,921 – a difference of 71,944 or 1.5%. The usually resident measure is used when analysing topics such as nationality and households and
  • For census purposes, a family is defined as a couple with or without children, or a one parent family with one or more children.
  • A private household comprises either one person living alone or a group of people (not necessarily related) living at the same address with common housekeeping arrangements – that is, sharing at least one meal a day or sharing a living room or sitting room. In order to be included in the household a person had to be a usual resident at the time of the census. Therefore, visitors to the household on Census Night were excluded while usual residents temporarily absent (for less than 12 months) were included.
  • This is the fourth of the eleven thematic reports of Census 2016 results. The CSO has also published two Summary Reports providing first results of all of the areas covered in the census. The next profile report, Profile 5 Homeless Persons in Ireland, will be published on 10 August. The remaining profile reports will be published over the rest of the year and will address themes such as commuting, Irish Travellers, ethnicity and religion, and employment, occupations and industry.
