Chapter 22 draws attention to various contexts in which the state compels citizens to disclose information about their personal and financial affairs in the course of their everyday lives. It begins by looking at how much information about property ownership is made publicly available by the Land Registry, and what steps can be taken to keep some of that information private. It explains the system by which documents containing ‘prejudicial information’ may be designated ‘exempt information documents’. Second, the chapter considers how much personal information is elicited by the decennial census, and how its confidentiality is safeguarded. Reference is made to the ongoing debate about the necessity for a traditional census, given the volume of data the government already holds. Third, the chapter summarizes the effect of the various statutory requirements for registration of births, deaths, marriages, civil partnerships, and adoptions.
