Population & Households


The total population in 2016 in Ireland was recorded as 4,761,865, an increase of 173,613 (3.8%) since 2011.  After a steady decline in population size, the first chart below shows an increase in the population since 1961.  The second chart demonstrates the percentage change in population in Ireland between 2011 and 2016, by county and by city.


It is important to track population growth, so that individual cities/counties and the country as a whole can develop plans and policies that will ensure that there is the capacity to meet the housing needs of the population. 

The Central Statistics Office produce a range of population publications and data tables, available here

Description: The chart shows the average household size in Ireland. Average household size (people per household) is calculated by dividing the household population by total households. Households include all persons living together, regardless of their relationship.

Importance: Average household size can be a reflection of personal or cultural preferences or economic choices. Anticipating changes in the size and composition of households is important for many housing-related issues and associated policies, including the needs of elderly single-person households, intergenerational housing options, and housing types to meet all life cycles.  Broadly, the changing composition of households may create a demand for the design and price of new housing types.
