[wdmmg-discuss] CRA data analysis

Dave

This is very interesting. Thanks for spending the time to explain it so 
thoroughly. Have you looked at matching spending by region (for schools, 
for example) with the aggregation of LA schools spending for that region 
from the 2006-07 Spending Report. It's now on OpenlyLocal 
(http://openlylocal.com/dataset_families/252). I haven't yet grouped by 
Region, but I'm planning to in the future, and I'd be interested to see 
if we can get the national and local figures to add up. I'm also seeing 
the Dept of CLG, who oversee the Spending Report on Tuesday, so if they 
don't can ask them about it (already planning on asking about timing for 
2007-08 report).

Cheers
Chris

In general, spending is classified using a scheme called COFOG: this defines a number of top-level functions, and each function is further broken down into sub-functions. For instance, pensions are part of the Social protection function, and Old age subfunction. More info about COFOG here: http://unstats.un.org/unsd/cr/registry/regcst.asp?Cl=4

Central government spending is performed by one a number of government departments, like the Dept of Transport, the Home Office, etc. Local authority spending gets grouped by area, depending on where the local authority is: England is broken down by region; Scotland, Wales and NI are pretty obvious. PESA doesn't differentiate between things like county, unitary authority, regions, etc: they're all grouped together as local authority spending.

> Spending can also be defined as identifiable or non-identifiable. Identifiable spending means that the money is spent for the benefit of a particular region, eg, pension spending for people in Wales. Almost everything is identifiable spending, even spending that goes outside the UK.

> By contrast, non-identifiable spending is spending that's thought to benefit the UK as a whole. For instance, much of defence spending, the civil list, national institutions, and the national debt fall into this category. (As does spending on the London Olympics, in spite of the word 'London'.)

> The CRA (county and regional analysis) data is a very large (25K rows) spreadsheet containing detailed spending breakdowns by department and program, so it offers much more granularity than PESA. What CRA allows us to do is take a look at a COFOG function or subfunction, and find out how the money is allocated between different spending programs, or between different regions. In theory, CRA should contain most of the raw information that was used to generate PESA.

We can also link up departments with their spending in terms of COFOG. For instance, we can look at a particular department and see how its spending breaks down by function, or do the reverse, look at a function and see which departments do their spending there.

> We have proper drill-down by programs. This means that we can look at spending programs in terms of how much money was spent on them, to find the biggest ones. We can do this for the uk as a whole, for countries, and for regions. For instance, we can look at Environment spending in the North West, and see that it's almost all due to the Nuclear Decommissioning Authority.

> The most fundamental issue in CRA is that none of the English local authority spending is broken down further than the top-level COFOG function. That means that for a region like, say, London, we can get local authority spending on social protection, but can't find out how that was divided between housing, sickness/disability, etc. Two consequences of that:
>

> - we can't generate the UK-wide COFOG subfunction breakdown just from CRA (but we can get it from PESA).

> However, in order to create the UK-wide subfunction breakdown in the first place, the people who compiled PESA must have the local authority spending broken down by subfunction, somehow. There are also additional PESA tables that can't be generated from CRA.

> The lack of drill-down for LA spending into English regions is a really big problem. We can get subfunction and program drill-down for the other nations, but not for England. This is painful since LAs are responsible for the majority of the spending of items like education.

> You can find an interesting spreadsheet on the CRA website called cra_form.xls, which appears to be the form sent to the Treasury by local authorities, and is supposed to contain their submissions to the PESA/CRA process. One of the sheets has contact information, so this could be a route to getting more detailed info.

(Here's an example: http://www.scotland.gov.uk/Publications/2009/06/18101733/0) And the treasury website contains a useful page pointing to a number of govt departments' reporting. (http://www.hm-treasury.gov.uk/psp_index.htm) I doubt it's feasible to do much with this kind of data in the short term, but perhaps it would be a useful exercise to at least identify what's out there.

In the meantime, I think there should be an action item to chase up the Treasury and see if we can get more detailed data, specifically to fill the hole in English LA spending. Who wants to take this up?
