3. Uses of Census data:
Provides census population estimates
Provides population characteristics on topics such as health, ethnicity, language, occupation, economic activity
Examples
The Fire Brigade - and other emergency services - use census statistics
Fire brigades across the UK use census statistics to allocate resources (appliances / personnel / fire engines) and plan home fire safety visits. Having the correct number of resources to respond to fires in the shortest time, and making visits in areas of high risk, can save lives
After-school lessons for grown-ups
The census is the basis of indicators such as quality of life, which show the need for more community facilities, like adult services making use of school premises after hours, for activities such as exercise classes and literacy lessons

4. Confidence in the results
There was a successful field operation for the 2011 Census and Census Coverage Survey. Return rates were good
ONS is confident that it will meet its national target response rate of 94 per cent and a target response rate of at least 80 per cent in every local authority
ONS is confident that fewer than 10 per cent of local authorities will be below a 90 per cent response rate
ONS achieved a Census Coverage Survey response
rate of 90 per cent
Census response rates will be published in the first release

5. Consultation process
Established the extent, scope and detail that census users would like to see for the 2011 Census outputs
A success in terms of the high quality of responses received, and the positive feedback on the proposed outputs for 2011 Census
Note : We will also be publishing a summary of our policy decisions including links to any changes.

16. Flow data
ONS is designing a wide range of specialist products for flows
These interactions (flows) include:
Migration
Commuter patterns

Second address to workplace address
Specs created by experts in this field and ONS have listened to user feedback from workshops held in October 2011
+ simple flows
+ and cross tabulated data

17. Microdata Series of microdata products: Public use microdataset
Building on the range of SARs produced in 2001 – possibility of increased sample sizes
ONS investigating the idea of a heavily perturbed (test) microdataset for users to develop syntax
Specs created by experts in this field and ONS have listened to user feedback from workshops held in November 2011 – increased sample size, moving back toward 1991
