Purpose
This document describes how Census 2021 data processing builds on methods from Census 2011, incorporating best practices from across the UK, Ireland, and internationally. The goal is to produce statistically robust population estimates, adjusted for non-response using a follow-up Census Coverage Survey (CCS).
It provides the aims and key actions for each of the main data processing stages:
- Data consolidation
- Data transformation
- Coverage adjustment
- Preparation for outputs
The document outlines a number examples of quality assurance checks that could be applied at each stage of processing.
