The first results from Census 2016, published on 14 July, show that the preliminary total of the population enumerated on Census Night, Sunday the 24th of April 2016, was 4,757,976 persons.The preliminary results, published just 12 weeks after census day, are based on a clerical summary of each enumeration area compiled by the 4,663 enumerators. These counts were returned to the CSO in advance of the census forms themselves and the results published are based on this information. We’d like to thank the enumerators and their supervisors for all their hard work over the course of the census. The CSO would also like to take this opportunity to extend our gratitude for the fantastic cooperation we received from householders during the conduct of the 2016 census. The preliminary results are the initial count of the census. Further results will be released in different phases as they become available during 2017, commencing with This is Ireland, Part 1 - Principal Demographic Results due to be published in March 2017.

What is the Census?

The census is a detailed account of everybody who is in the country on census night. On 24th April everybody is Ireland was required to enter their details on a census form.

The importance of the census is that it accounts for everybody in the country no matter where they are. The results provide invaluable information on not only population size for the country as a whole, but also about the make-up of the population of towns, villages, and other small areas across the country. As well as collecting information on the age and sex of the population, a range of different questions relating to households and individuals are also asked such as where and what people work at, how people travel to work, school and college, languages spoken, disabilities, families, housing and lots more.

Who conducts the Census?

Fraudulent Phone Call Alert

26th August 2016

The Central Statistics Office (CSO) wishes to alert members of the public to a phone call scam to solicit personal details from unsuspecting victims. Members of the public have alerted the CSO that they have received suspicious calls from persons claiming to be working on behalf of the Census and seeking personal details. These calls appear to be originating from outside of Ireland. These callers do not work for the CSO nor do they have authorisation to make these enquiries on behalf of the office. The CSO will never contact members of the public seeking personal Census information over the telephone in this manner. The CSO advises people who receive suspicious calls from individuals claiming to work on the Census to end the call immediately and to notify their local Garda station.
