I realise this isn't strictly a 2011 Census issue.  However, now we have revised LSOA boundaries for the census data, does anyone know if there are plans to produce an update to the Indices of Deprivation 2010 for the new boundaries?  I'm getting a number of enquiries about updates but can't find anything on the DCLG website.  Grateful for any insights.

Do you mean reissuing the IMD2010 on new LSOAs, or a complete new IMD on the new LSOAs?
I'd be very surprised if CLG were to rework the old IMD as all the data would need to be recast, so it would be a major effort for arguably little benefit. I guess it could be done yourself by reworking the scores, but it would still be a hassle.

We've been told that CLG are going to consult on the future of the IMD 'shortly', though that was in January! What the content and geography of a new IMD would be are anyone's guess. It would make sense to produce the next IMD on the new boundaries, though this presumably depends on data being available on the new LSOAs boundaries. And presumably, the question of data is going to be tied up in the major changes to the benefits system including Universal Credit.

Alison,

Revisitng IMD 2010 to accomodate the new boundaries would be a major exercise. (The ranks of the new set of LSOAs would need to be recomputed, etc.) . My understanding, having discussed the matter with ONS,  is that ONS has attributed IMD scores  to the new LSOAs based on the scores of their "parents". So, if an old LSOA is now divided into two, each of them inherits the score of their successor. LSOAs formed by merging others have a population -weighted average and so on. At any rate, this is the approach they have used in regressions involving IMD.

No doubt this will be revisited if and when the English Indices of Deprivation  in 2013.

Hope this helps.

Charles

Thanks for your question, Alison.

DCLG will not be re-issuing existing English Indices of Deprivation (ID) using the new LSOAs. As others have commented, the ID 2010 reflect a range of historic data, mainly from 2008, which was collected or compiled for each LSOA in England. It would be a substantial task to re-collect or re-compile data using the new LSOA boundaries, assuming such data are even available. This is in line with general guidance on production of small area statistics that used pre-2011 boundaries.

We are assessing options for updating the Indices. Where possible, a new set of indices would reflect the new LSOA boundaries and incorporate relevant Census data.  

The IMD team can be emailed at indices.deprivation@communities.gsi.gov.uk, and our website has moved to: https://www.gov.uk/government/publications/english-indices-of-deprivation-2010.

Is there is anything we as LAs can do to provide evidence of the potential demand for the IMD update with new boundaries?

Just to clarify I was thinking of an update with new data fitted to the 2011 boundaries, but the tips on relating the ID 2010 to new boundaries are helpful. Thanks for all your comments.

Dear James

Thank you for your offer. In assessing options for updating the indices, we have already had helpful input from LGA and the Public Health Observatory Network. While we are not seeking further input at this stage, we anticipate wider consultation as proposals develop.

Hi all

Whilst they may not be the IMD, I have a file with Townsend and Carstairs deprivation scores and population weighted deciles calculated using 2011 Census data for LSOAs. These are calculated for England & Wales combined, England only and Wales only. If the file may be of use then please get in touch.

When time and data availability allow I will extend to Northern Ireland and to Scotland.

Best wishes

Paul

Message:

Dear Alison,

 

At Public Health England we are planning to revise the current IMD-2010 scores so that they align with 2011 LSOA boundaries. We are proposing to do that by identifying LSOA s which have been split or merged between 2001 and 2011. Where LSOAs have been merged, we plan to calculate a population weighted average of their IMD scores to assign to the new merged LSOA. Where an LSOA has been split, its IMD score will be assigned to all the resulting LSOAs.

 

Our proposal is currently with DCLG and ONS to allow them to comment. PHE needs the revised IMD scores in order to calculate health inequality indicators for the Public Health Outcomes Framework and local authority Health Profiles. We plan to assign the revised LSOAs to deprivation deciles/quintiles within England, and within local authorities and other geographies. We hope to make the assignment of revised LSOAs to deprivation categories publicly available.

 

Our proposed approach is essentially the same as outlined by Charles Arthurs in his reply which noted what ONS are doing. We have been in contact with ONS, as we will be sharing the revised scores with them, but are not aware of anyone else at ONS who might be doing this work.

 

Best wishes,

 

Allan

That's interesting, thanks. Please keep us informed as to progress.

I suspect that such reworked results will be especially useful when/if a new IMD is published! Presumably that would be published on the new LSOA boundaries, so a ready source of IMD2010 data on the same boundaries will make comparisons of new and old IMDs relatively easy.
However, I'm sure we'll be told that we can't compare the two analysis, but I suspect that won't stop us.....

It occurs to me that if Allan's methodology is applied to the subdomains of the IMD, the exponential transform applied to the revised LSOAs ranks, and a weighted average taken,  one will get get a different revised IMD score from that obtained applying his method directly using the previous IMD scores. This would involve a lot of extra effort and the gains may be negligible. It would, however, be more rigorous.

Thanks for the update - that resource will be most useful pending publication of a full update to the ID 2010.  Have you any idea of a time frame, and will the resource be available on the PHE website?

Allan,

Its worth remembering, that although the majority of 2011 LSOAs were either splits or merges of 2001 LSOAs allowing some level of recasting, there are a small minority of LSOAs where this is unlikely to be possible.

In some cases, LSOAs were changed as a result of consultations or local authority boundary changes and were therefore not straightforward splits or merges. These changes were indicated with an 'X' on the LSOA lookup to indicate that recasting should not be attempted for these geographies, and you would therefore need to a different methodology to deal with these, than the one you have proposed for the splits and merges.

Public Health England has now released adjusted scores from the English Indices of Deprivation 2010, to align them with 2011 LSOA boundaries.   

The adjusted scores can be used for analytical purposes where data are required for 2011 LSOA-level geographies. The adjusted scores do not replace DCLG's official English Indices of Deprivation 2010, which are based on 2001 LSOA boundaries.

Two sets of scores have been adjusted: the overall Index of Multiple Deprivation (IMD) and the Income Domain. Each file contains a set of adjusted scores, with details of how the adjustments were made. The adjusted scores have also been used to assign 2011 LSOAs to deprivation quintiles/deciles within England as a whole and also within English regions, counties, and local authorities.

The adjusted scores are available here: http://www.apho.org.uk/resource/view.aspx?RID=125886
