Age is one of the most commonly used census variables. It is regularly used to help analyse other census variables (eg work and labour force status, tenure holder) and to investigate population ageing. Age data from the census also provides the base population (ie denominator) for fertility, mortality, morbidity, suicide, accident, and crime statistics.
Our current recommendations relating to age
Collecting age is required by law under the Statistics Act 1975, so must be included in the census.
No changes are recommended for age.
See our preliminary view of 2018 Census content (page 14)for a more detailed discussion on age information.
See 2013 Census information by variable for information on the age variable.
