Overview

The UK Censuses constitute one of the most important data collection exercises undertaken by the UK Governments. Public confidence that personal census information will be securely handled is a vital ingredient for success.

Information Assurance Policy Statement by the UK Census Offices

The 'Information Assurance Policy Statement by the UK Census Offices' outlines the policy and commitments that the three UK Census Offices have adopted on Information Assurance (IA) for the 2011 Census.

All three Census Offices have given firm undertakings that this data will be used solely for statistical purposes, and that it will be treated in strict confidence. The purpose of this report is to present the findings of an independent review of the extent to which these undertakings will be met.

The first report '2011 Census Security: Initial Report of the Independent Review Team' was published in February 2011, when the Census was about to go live.

Final Report of the Independent Review Team

The '2011 Census Security: Final Report of the Independent Review Team' is the final report of the independent review team and has been composed after the main data capture and processing stages have been completed.
