That is very interesting, but if a percentage (say 10%) is moving to 
urbanised areas - then rural municipalities should be shown on a 20% basis ?

Residential building information talks to a shift of population profiles and migration issues as reflected by Stats SA data, so past performance on tight margins may change the game plan at where it matters, the municipal level elections.

I believe that a better method would be to colour code the winning party, and write its victory total (ie 55% of all votes) and its margin of victory in percentage (by ward) - ie if the winning party got 55% and the next party got 35%, then it won by 20 points.

Of course their may be better ways, but with a title aimed at 2016 I do think it should reflect percentage victories to portray to people the possibilities in that data - how safe it is, perhaps with a merger it could change, if people of one party dont vote because of a viable alternative - who would win etc... - a whole miriad of possibilities.

Have a look here: http://www.elections.org.za. You'll find the results for all the elections that have taken place over the past two decades or so, down to the voting station. I got the shapefiles from www.demarcation.gov.za <http://www.demarcation.gov.za> .

I defined contested as there being a less than 10% difference in vote counts between the first and second place winners. I'm by no means a cartographer and this is one of my first projects so I was hoping for comments about how one might improve the maps. I guess the one problem is that even though you know that a ward is contested, you don't know by how much. Also (and i'm not sure this is important) you don't know from the map what the individual wards are - only the municipality they are in. Finally, I don't know where most of these municipalities are situated so perhaps so sort of contextual map showing them in relation to the rest of the country might be useful. Of course all of these things are possible but might not be easy to achieve while still maintaining an uncluttered design. Any advice would be appreciated.

Hopefully this sort of question is not frowned upon in this forum (if it helps, everything here was produced with open source tools :)). Great project! Is the source data you used available somewhere publicly? If so can you provide a link to it?
