<strong>Synthesis</strong> <strong>Report</strong><br />
economic perspective. One of the consequences of this is that commuter flows, instead of taking<br />
place largely within regions, cross regional boundaries to a significant extent and, moreover, tend<br />
to be in one direction, either into or out of regions. This means that the commuters concerned<br />
contribute to the GDP in the region in which they work but are not counted as part of its<br />
population, which accordingly pushes up GDP per head. It also pushes down GDP per head in the<br />
region where commuters live since they do not contribute to its GDP but are counted in the<br />
‘heads’ over which it is measured.<br />
Commuting is an important reason for the pronounced disparities in GDP per head between<br />
regions in a number of countries indicated above (see Box). It is also a potential reason for the<br />
differential rates of GDP per growth indicated above. If, for example, people living in an Objective<br />
1 region moved out to live elsewhere but continued to work in the region, then GDP per head<br />
would have risen because of the fall in population without any growth in GDP occurring as such<br />
(see Box for examples). It is, therefore, important to make an explicit adjustment for commuting<br />
in order to distinguish ‘genuine’ increases in GDP per head from spurious ones, so as to be sure<br />
that the narrowing of disparities in GDP per head over the period was a real phenomenon 14 .<br />
In practice, according to the data available – which are relatively uncertain and, accordingly<br />
should be regarded as indicative only – commuting did not change a great deal over the<br />
programming period. Indeed, net outward commuting from Objective 1 regions seems on average<br />
to have increased slightly, which suggests that the rate of growth of GDP per head indicated<br />
above may understate the increase in their economic potential which occurred.<br />
The small increase in outward commuting from lagging regions, by depressing their GDP per<br />
head, tends in itself to widen regional disparities measured in these terms. Adjusted for the effect<br />
of commuting, disparities in GDP per head between regions in the EU15, therefore, narrowed by<br />
slightly more than indicated above (Table 2.6).<br />
The effect of commuting is especially marked in the UK, where the relatively wide disparity in GDP<br />
per head between regions owes a great deal to this effect. After adjusting for commuting, the<br />
degree of disparity in GDP per head in 2006 was much the same as in 2000. The effect of<br />
commuting on regional disparities is even more pronounced in Belgium, but here the effect is<br />
slightly weaker in 2006 than in 2000 because of a small decline in flows. Adjusted for<br />
commuting, therefore, regional disparities in GDP per head widened a little over the period. This<br />
was also the case in Portugal, though the degree of widening was less.<br />
14 The adjustment is made by relating the number of people employed in a region, including both those who are<br />
resident there and those who live elsewhere, to the number of people living in a region who are employed either in<br />
the region or outside. This gives a ratio which can be applied to GDP to allow for the effect of commuting:<br />
(Er+Eo)/(Er+Or)<br />
where Er is the number in employment in the region who live there, Eo is the number employed in the region who<br />
live in another region and Or is the number in employment in a region who work in another region. If the ratio is 1,<br />
then the same number of people travel to work outside the region as travel in to work and commuting has no effect<br />
on regional GDP per head. If it is positive, then more travel in to work than travel out and vice versa if it is negative.<br />
