The 1996 census is being taken on Sunday, 28 April 1996. The census covers all persons present in the State on that night. Persons are enumerated in the households or institutions in which they spend the night of 28 April 1996. In common with other population groups, third level students are enumerated in the census wherever they pass census night.
There is a legal obligation on heads of households and institutions to provide the information requested on the census form in respect of every person present in the relevant household or institution on census night.
The census is taken on a de facto basis, that is, the population recorded for each area represents the total of all persons present within its boundaries on census night together with all persons who arrived in that area on the following morning not having been enumerated elsewhere. In order to avoid gaps and duplication in achieving a full and accurate count of the population, it is essential that a consistent approach is adopted to the enumeration in all circumstances.
Sunday night has traditionally been chosen as the reference point for the census as it is the night most persons can be expected to be at their usual residence.
