The Census of Employment is carried out every two years. It is a survey of all employers in Northern Ireland which must be completed by law under the Statistics of Trade and Employment (Northern Ireland) Order 1988. It covers employee jobs only and excludes, for example, self-employed, HM Armed Forces, homeworkers and Jobskills trainees without a contract of employment.
