From
Of Devolution, Maps and Divided Mentalities
by Paul O'Leary, Planet 127:

So, Wales has a newly-minted icon for the millennium. No, not the symbol of unity the new National Assembly might become, nor even the new National Stadium which is slowly rising near the banks of the River Taff out of the rubble of the past. Our new icon is the divided map of Wales, constructed out of the results of the devolution referendum, which depicted a red No-voting east angrily facing a green Yes-voting west. Our divisions, it seems, are enshrined in territorial antipathies....

...The referendum was not a confirmation of old and entrenched attitudes so much as a snapshot of an electorate whose attitudes are in flux. The fundamental changes which have taken place in Welsh society over the last eighteen years are reflected in the telling statistic that whereas the swing in favour of devolution in Scotland since 1979 was a little over 20 per cent, in Wales it was 30 per cent. Like the divided map, the concentration on entrenched territorial divisions was largely a creation of media reports.

We require new charts to navigate the unfamiliar political waters we shall be entering when the National Assembly meets for its first and truly historic session in 1999. The cartographical representation of the results of elections to the National Assembly, which will include a combination of first-past-the-post and proportionality, will challenge the ingenuity of political analysts. In the meantime, we have the maps of the referendum results to suggest how we might get to that destination. Professional geographers will, no doubt, find more sophisticated ways of representing the data than I have been able to outline here. In the meantime, let's not forget that icons are not for passive obeisance. In our search for inclusivity, we ought to get at least that right.
