2011 / 2001 data comparisons


DRAFT - PLEASE DO NOT COMPLETE AND SUBMIT FORM

Results from the survey show that there is strong demand from users to be able to make comparisons between 2011 and 2001 Census data. The specific continuity between censuses in areas such as population base, geography, and variable definition will all have an impact on the degree to which logical comparsions can be made and therefore be of use to users. User preferences and some technical issues may further influence specific areas of user needs when it comes to accessing comparisions.

Overall almost 83 percent of users said they would need to make comparisons. These results will be discussed further in a future post which will include additional fine detail about needs by user sector and level of geography.

Ahead of that, and as a source to inform discussion when these results are posted, we would like to ask for some additional feedback using the form below.

The survey questions did not ask about the methods and tools that users have or intend to use to make comparisons

  • whether users want the data itself to be intuitively comparable, but make actual detailed comparisons themselves using the 2 distinct data sets in their own systems, or
  • whether users want the 2 data sets co-located in a web based system to allow quick, frequent but less complex online comparisons to be made.

The survey asked about the levels of geography for which users will want to make comparisons, including a bespoke option, but did not cover in depth lower level areas below Local Authority District (LAD) - such as ward, parish, Output Area, or health geographies.

No firm plans or commitments have yet been proposed or developed by the Census to make available any form of online comparisons, but we are interested in guaging the level of user interest for such a system that might allow higher level or less complex comparisons. Alternatively some users might prefer to see more attention devoted to delivering a richer set of data for comparison in users own systems.

So we are asking………..


Current wards, and OA boundaries

The reality of local politics and grant allocations requires that data sets are available for local authority wards current at the time of the data analysis. MSOAs are of no benefit for this purpose, LSOAs only so long as they continue to nest into wards.

There is also a desperate need to tweak Output Area boundaries so that they are recognisable on the ground: that they run along the centre of roads and streams, face of fences and walls, between boundary stones, etc. This is for the most part technically achievable: the anomalous parts of OAs generally contain no residential properties; anomalous OA boundaries rarely pass through them. Snapping to physical features in this way would be worth the effort (if not the spurious expense of commercial charges by Ordnance Survey and the Royal Mail) and would greatly increase the acceptability of census data to general users.

Unfortunatley this battle has already been lost with the decision being made that a stable geography was the most important consideration.

I'm not challenging the principle of a stable geography, which has my full support. What I'm asking for (and not alone in this) are boundaries that do not zig-zag across areas where there are no residential buildings that would require it.
