Risks and issues
• Undermine response to the 2011 Census• No population register• Data quality• Maintenance• Public attitudes• Cross-government support• Funding
Advantages and disadvantages of alternative data sources
Census • Well established • Rich data• Flexible• Small populations• Accurate• Checkable• A known quantity
But• Snapshot in time• Infrequent• Expensive• Burdensome• Dependent on public response
Advantages and disadvantages of alternative data sources
Surveys
• Rich data• Reactive• Low cost• Frequent
But• Sample only• Estimates• Still some burden• Declining response rates
Advantages and disadvantages of alternative data sources
Administrative registers
• Minimal cost• Less burdensome• Continuous• High granularity
But• Non statistical• Variable coverage • Variable quality• Not all census topics covered • Inflexible• Non-comparable• No control• Legal issues
Data models and potential options
1 The Census provides a population spine

3 A survey or rolling census is used
Conclusions
• Early days
• Options to be reviewed and assessed
• No decision on traditional 2021 Census yet
• Strong requirement for a culture change
