First results

The census 2016 results are released in different phases as they become available. The first to be released was the Preliminary Population Report which was published on the 14th of July 2016, just under 12 weeks after census day. This report contained the total population of males and females in each Electoral Division across the country and was based on summary data taken from the front of the census forms.

The subsequent results are published once all two million census forms are scanned and captured, a process which takes about 7 months. Results are then prepared for publication which takes another couple of months. The first of the full final results were published on April 6th 2017, less than a year after the census date, April 24th 2016.

Interactive web tables

Each Census Release is accompanied by a wide range of census tables that are available as interactive web tables on the CSO website. All data is available to download to in csv, excel and other formats. These results are available in tandem with the Census Releases.  You can check out our 2016 interactive tables to date here.

Small Area Population Statistics

The real strength of the census is the provision of real meaningful data for very small areas and the Small Area Population Statistics (SAPS) are one of the most popular products. For 2016 the areas for which the tables are produced include the 19,000 new Small Areas (which typically contain 50 – 200) dwellings. The tables are available both thematically (for example tables on nationality available for all small areas together) and by area (all tables for a particular area).  To see the SAPS results for 2016 click here

Interactive web maps

The small area population statistics are available to view using the SAPMAP  tool. This mapping tool allows users to pan and zoom to their area of interest using different boundary layers. The user can then view the SAPS for that area. Check out the interactive mapping search tool here.

The CSO work in collaboration with the All Ireland Research Observatory (AIRO) who produce interactive thematic maps covering a range of themes. The Census 2016 maps can be found here.

Area profiles

For census 2016 it is planned to release summary profiles for particular geographic areas, such as counties, constituencies and towns. The two page report will contain summary census results on a selection of key demographic and economic variables.

The 2011 area profiles can be found here.  The 2016 area profiles will be available in the coming months.

Place of work school or college – anonymised records

As part of the Census 2016 processing programme the place of work, school or college details are geo-coded. All workers resident in Ireland on Census night are coded to their place of work and all Irish resident students from the age of 5 and upwards are coded to their place of school/college. A detailed file containing the demographic and socio-economic characteristics of these residents along with information on the origin and destination of their journeys is available for analysis.

The POWSCAR file is only available under strict conditions to bone fide researchers who are approved by CSO. More details can be found here.

10% sample of anonymised mircrodata

The CSO will provide a 10% sample of anonymised records to Integrated Public Use Microdata Series, International (IPUMS). This harmonised data allow researchers to carry out social and economic analysis across over 80 countries and hundreds of census datasets. More details can be found here.
