  • Access and archiving policy

    The ICP Data Access and Archiving Policy (PDF), as approved by the ICP Governing Board, outlines the objectives, guiding principles, and procedures for data archiving and researcher access to underlying detailed PPPs, expenditure data, and average prices.

    Revision policy

    The ICP Revision Policy (PDF), as approved by the ICP Governing Board, sets out the policy, triggers, and procedures for revising previously published and unpublished results from the ICP, to ensure the program’s outputs reflect the latest available information and methodologies, are of the highest quality, and remain relevant to users. It describes the timing of revisions and the steps to be taken to communicate these revisions to users.

  • The ICP Quality Assurance Framework (ICP-QAF) (PDF) was developed under ICP 2011 to ensure the quality of ICP activities and results. The framework introduces rigor, structure, and a common language in the assessment of the quality of microeconomic data and aggregated results and the implementation of relevant processes.  It comprises principles that ICP procedures at the country, regional, and global levels should adhere to.
