This preliminary report presents the first results of the Census held during October and November last year. It is the 18th in a series of population censuses dating back to 1842. Nationally, its legal basis is the Census Act of 1948. At the EU legislative level, Census 2021 is the second census to be carried out according to the provisions of European Regulation (EC) No 763/2008 on population and housing censuses. From different angles, Census 2021 had many innovations.
First, the modes of data collection were diversified to accommodate modern needs. Therefore, in addition to the traditional paper questionnaire, there were alternatives such as personal interviews with data capture on tablets, telephone interviews and web completion through an online form. Second, the questionnaire was updated following a full consultation process locally and also took account of international needs. Third, at the results stage, in addition to the usual detailed census information, Census 2021 will present added value to the evolving world of spatial analysis in the shape of 1 square kilometre grid datasets. As the analysis proceeds, all this and more will be published in a series of Census publications, of which the preliminary report is the first.
