The CRA data is in the data store, and we're using it to generate queries.
The first thing to notice is that we don't get the same TME (Total Managed Expenditure) numbers that we did in PESA. Our numbers are a little lower. Thankfully, the difference is easy to explain. The numbers that we come up with correspond almost exactly to the Public sector expenditure on services (PESA table 5.2), and the difference between that and TME is contained in a line marked 'Accounting adjustments'.
So that people know how close we're getting, the official numbers for 2003-2004 up to 2007-2008 are:
This gives us a lot of confidence that we can derive many of the PESA figures straight from CRA.
The downside is that the figures for 2009-2010 and 2010-2011 are unreliable. The totals are significantly less than the 2008-2009 figures, ie, more than 20% less. Since these figures are projections, I think the best guess is that they're computed with incomplete data.
Anyone have good ideas what we should do here?
