The Central Statistics Office (CSO) has launched its campaign for Census 2016, which will take place on Sunday, April 24.
The forms have already started to be delivered, and everybody who spends that night in Ireland must be included on a census form.
The last census was carried out five years ago, and this year’s will remain unchanged apart from one question which recognises the legal status of same sex marriages.
Speaking at the launch of the campaign, caretaker Taoiseach Enda Kenny outlined its importance.
“By participating in the census on the 24th April, each and every one of us will help to shape our understanding about life in Ireland today”.
“We will also show how, as a country, we have changed and are changing over time. Importantly, it will also equip us to plan for the Ireland of tomorrow”, he added.
