Birmingham Council Elections 2007
The picture below shows the percentage of votes obtained by each party in each ward. Red indicates a low vote, green the highest. A clear clustering of wards is visible, with the lower half of the diagram dominated by wards with a high Tory vote, the centre by Lib-Dem (mainly with Labour in second place) and the top by Labour wins. If you know the geography of Birmingham, you'll notice that some of the wards which vote similarly are close together (as we might expect), for example, note the four "Sutton..." wards listed at the bottom right.
The data was drawn from the Birmingham City Council website, and is believed to be correct, but I have not gone through and hand-checked every result. You can download the election results data file (csv)
if you'd like.
Party's Eye View
The diagram below has been adjusted to show more detail on the performance of individual parties. The colours indicate the best and worst performing wards for a party. For example, Harbourne and Bourneville are the wards in which the Green Party got their highest percentage, and are shown as green. However, these wards were actually won by the Conservative Party, where the yellow rectangles indicate they are in the middle of that party's list of wards by votes obtained.
