The census in all UK countries has been undertaken in a consistent manner. However, there are differences in some of the questions asked, processing, and detailed methodology.
Before using census data you should ensure that the census covers the right topics for you. Questions and definitions often change between censuses. You can access the census forms, definitions, and the census agencies websites for further information.
