[1] It was organised by the Central Statistics Office (CSO) and reported a total population of 5,149,139, or an 8.1% increase since the prior 2016 census.

[8] Preparation of the 2022 census form began in 2017 with a public consultation process drawing input from various governmental departments, interest groups, and academics.

[9] The consultation was organised by the Census Advisory Group between October and November 2017, assessing over 400 submissions which informed a test survey of revised and new questions in September 2018.

[10] The consultation process led to the inclusion of 8 new questions, which covered topics like ownership of renewable energy sources, working from home, and smoking habits.

The 2022 form was also the first to include a 'time capsule' section, offering a space for respondents to write a voluntary message to remain sealed for 100 years due to data protection requirements.
