Deprivation in your area - search and zoom

After making a new website when the Scottish Index of Multiple Deprivation 2012 was released, I've been looking at some of my old English IMD web pages and tools and so have decided - in anticipation of the next update to the IMD - to add a 'search and zoom' tool so that anyone who is interested can find out what deprivation is like in their area - or any other area of England you are interested in. Like my previous versions of this kind of thing it's based on Google Maps but in the version seen in the screenshot below you can simply enter a place, neighbourhood, postcode or address (or even an organisation, like Centre for Cities) into the search box and it will go straight there after clicking 'search'. Click the image or the link below to use the tool.

IMD Search and Zoom

As usual with these kinds of maps, if you click on an area the pop-up will give you more information. The next update of the IMD was to have been in 2013 but I'm not sure if that is still going to happen. However, I've updated this tool just in case so that I can add in the next update whenever it becomes available. The Scottish version of this tool is on this page, but I have not yet done the same for Wales or Northern Ireland.

Children in Poverty

I think I've already said enough - and done enough mapping - of general deprivation indices across the UK. Well, probably. Either way, I thought it would be interesting to take a slightly different view. In England, the Indices of Deprivation 2010 include two supplementary indices: the Income Deprivation Affecting Children Index (IDACI) and the Income Deprivation Affecting Older People Index (IDAOPI). Not very catchy acronyms, and these indices are not that well known, hence my efforts to map the IDACI data for England (screenshot below)...

The map I've produced in Google's Fusion Tables follows the format of many others I've done, but this time I've summarised the data using 2010 parliamentary constituencies - following the same method that the IMD people use to derive summary measures at the local authority level. On the main map, you can find out how deprived a constituency is (i.e. the relative rank in England) by clicking on it. Red = more deprived, blue = less deprived. Using this method, the constituencies with the highest levels of income deprivation affecting children are as follows:

1. Poplar and Limehouse
2. Bethnal Green and Bow
3. Manchester Central
4. Tottenham
5. Hackney South and Shoreditch
6. Birmingham Ladywood
7. Islington South and Finsbury
8. Edmonton
9. West Ham
10. Birmingham Hodge Hill

The really noticeable thing here is the number of London constituencies. In the general IMD for England, it is areas in the North West which dominate, but not here. As to why this is, there are many reasons but that's not the point today. Why not explore the national patterns on the map and see how your area compares (if you live in England). The most important thing about all this is, of course, the fact that so many children in England are adversely affected by income deprivation.

Divided Cities?

There has been a lot of talk recently about the links between deprivation and the recent riots in England (e.g. this from the Guardian), and since I'm interested in the issue I thought I would do some very basic analysis to look at the spatial divisions of deprivation in English cities. To do this I took London, the eight core cities plus Bradford, Coventry, Hull and Leicester and mapped the 10% most (in red) and 10% least (in blue) deprived (IMD 2010) areas on one large map graphic. The results are shown below - click the image to enlarge.

Some interesting comparisons can be made from this image. In Hull, Leicester, Manchester and Nottingham there are no areas amongst England's 10% most deprived and in Liverpool there is only one. In Sheffield there is a clear NE/SW split in terms of the location of the most and least deprived and in Manchester, Birmingham and Liverpool the number of areas in the most deprived 10% is quite high.

Not much else to say now except that I think in studies of deprivation we should perhaps be more concerned with inequalities and how they manifest themselves spatially.

IMD 2004, 2007, 2010 - Change Over Time...

This is the last deprivation-related post in a while. I promise. I've been experimenting with English IMD data from 2004, 2007 and 2010 and have finally found a moment to do to it what I did to the Scottish IMD data, where it is all online and clicking an area produces a chart showing change in rank through time. In this new example, I've also added in the change in rank between 2004 and 2010, as you can see below. The rank change doesn't tell you if an area became more deprived in absolute terms, only that it is less or more deprived in relation to the other 32,481 LSOAs in England.

You can see in the example above a case of a quite large change in rank. This is for an LSOA in London. The maps are quite basic because I don't have time right now to build a more sophisticated site but the colour scheme is based on quintiles, with red most deprived, yellow next and blues less deprived (the darker the blue, the less deprived), as below.

For the moment, I don't have any plans to extend this analysis to Wales or Northern Ireland, but you never know...

The IMD in 3D

Before I move on from experimenting with the deprivation data from the new English Indices of Deprivation I thought I'd do a 3D version, just for fun. The images below are the results of my experiments. The first image has labels for various places. The second image does not and is also at a higher resolution.



When you add a third dimension certain places stand out more (e.g. coastal areas) but there is a balance to be struck here, as always... That's enough IMD mapping for now!

The Domains of the IMD

What most people look at when they see the Indices of Deprivation is the combined Index of Deprivation score and rank for each area. I do this too, but it's always interesting to examine the individual domains to see how areas rank and what the spatial patterns look like. So, time for a map on all of this... (click to enlarge)

In the above image, you'll see that I've produced a raster map for each of the different domains of the English IMD 2010 and that each is sized according to the percentage weighting it gets in the final IMD. There are some interesting differences between domains which, by the way, are covered in Chapter 3 of the technical report.

Income and employment account for nearly half of the weighting for the final IMD score so these maps look pretty similar to the overall IMD map but there are interesting differences with other domains, in particular Barriers to Housing and Services. This picks up a lot of rural areas but also many in London and some other urban locations. Health deprivation and disability also differs from the final IMD map with a more obvious north-south / coalfield pattern. Finally, the most deprived LSOA on each domain is as follows...

• Income: E01005482 in the Central and Falinge ward of Rochdale
• Employment: E01005482 in the Central and Falinge ward of Rochdale
• Health and Disability: E01005482 in the Central and Falinge ward of Rochdale
• Education, Skills and Training: E01013640 in the Braunstone Park ward of Leicester
• Barriers to Housing and Services: E01000604 in the Stonebridge ward of Brent
• Crime: E01005454 in the Waterhead ward of Oldham
• Living Environment: E01001780 in the Hoxton ward of Hackney

The fact that these domains are in different spreadsheets makes mapping it all a bit more time-consuming but since I combined them all anyway I decided to create raster versions just to provide a more fluid overview of the patterns across England. I'm sure I'll keep milking this data for a while!

English Indices of Deprivation 2010 - A North-South Divide?

I've been looking at the new Indices of Deprivation a bit more since my last post. Despite the headline-grabbing fact that England's most deprived area is in Essex - in the south of England - the overall patterns remain dominated by the North. This map highlights the least and most deprived areas in England and also notes some important exceptions (click map for full size image)...


I've also put together an animation showing the 1%, 2%, 3%, etc. most deprived areas all the way up to the 10% most deprived - and then the 10% least deprived (as in the map above) in order to demonstrate the general north-south divide. Notice how the cities of Liverpool and Manchester in particular dominate these patterns. If you want to control the animation, you can hit pause then move the slider along the time bar yourself (the video may take a moment to load).



This version is just a small blog size version - I've also posted a larger version on my University of Sheffield pages. So, in contrast to the headlines, it seems clear that deprivation remains more firmly entrenched in the north than in the south (with some exceptions of course).

Indices of Deprivation 2010

The English Indices of Deprivation 2010 were published this morning. Previous Indices were published in 2000, 2004 and 2007. I've decided to do a few posts on this because I find it very interesting and it does have real implications in relation to policy. In this post, I've done some basic mapping and analysis (click on any map to view it full size).

A quick snapshot first: the most deprived LSOA is in Tendring, Essex. It used to be in Liverpool. Overall, Liverpool, Middlesbrough, Manchester, Knowsley, Hull, Hackney and Tower Hamlets remain the most deprived local authorities. So, no major surprises.

Note: The Indices of Deprivation 2010 are produced for small areas called LSOAs. These lower layer super output areas are not 'neighbourhoods' in a formal sense but they often have a high degree of internal similarity. The average population of an LSOA is about 1500 and in total there are 32,482 of them in England. The data used in the Indices are mostly from 2008 but you can read more about this in the technical report.
