Box The mean logarithmic deviation index<br />
The mean logarithmic deviation index is defined as:<br />
1<br />
I =<br />
n<br />
∑<br />
i<br />
ln<br />
⎛ μ<br />
⎟ ⎞<br />
⎜<br />
⎝ y ⎠<br />
i<br />
Where n is the number of observations, μ is the average GDP per head, and yi is the GDP per head<br />
of a region i.<br />
In calculating the index, each region is weighted by its population in order to allow explicitly for<br />
the large variation which exists in the size of regions and to give a more accurate measure of<br />
regional disparities across the EU. This is important since unweighted indices, which are often<br />
used, show significantly different changes. Other measures of disparity, such as the standard<br />
deviation or variance show similar results, so long as they are population weighted.<br />
This overall reduction in disparities was a result primarily of the catching up of regions in the<br />
EU10 countries where in both periods, as seen above, GDP growth was much higher than in the<br />
EU15. If regions in the EU15 and the EU10 are considered separately, the change over the period<br />
was less clear-cut.<br />
