Edmonton Election 2010: Election Result Statistics

By now I’m sure you’ve seen the unofficial election results (official results should be released tomorrow). I thought it would be interesting to look at those numbers in more detail, and with a little bit of context.

There were 14 data updates throughout the night. The first voting stations reported in at 8:31 PM, and the final one reported at 11:35 PM. Here’s what the updates looked like:

Time is along the bottom, the vertical axis represents the number of ballots cast, and the size of the balloon represents the size of the update (the data labels are the number of votes after the update). You can see that there was one very large update, at 9:48 PM.

Here’s what Stephen Mandel’s win looked like throughout the night – the difference in votes between him and nearest competitor David Dorward:

When all was said and done, Mandel had won re-election by 49,533 votes.

A total of 196,661 ballots were cast. Here are the number of votes per ward:

You can see that Ward 8 had the most votes. Because the wards changed this year from six to twelve, it doesn’t make sense to try to compare them to 2007. We can compare the winning candidates however. To get elected in 2007, a candidate on average had 12724 votes. To get elected in 2010, a candidate on average had just 8640 votes.

Here is the difference between first and second place for each ward:

You can see that the two closest races were in Ward 2 and Ward 3. Those two wards were among the busiest in terms of the number of candidates, along with Ward 6 and Ward 11. The biggest wins were in Ward 5, Ward 9, and Ward 10, all of which had strong incumbents and few competitors.

Here are the number of votes per Catholic School Ward:

And finally, here are the number of votes per Public School Ward, compared with 2007:

There were two acclamations this year, versus just one in 2007. In every other ward, the number of votes in 2010 was higher than in 2007. This isn’t surprising, given the increased interest in schools due to the closures.

Just 1217 ballots did not indicate a choice for mayor (compared to 2491 in 2007), where as 4456 ballots did not indicate a choice for councillor. A total of 44,121 ballots did not indicate a choice for school trustee (keep in mind there were two acclamations, but still).

I’ll leave you with this:

UPDATE: Official election results are now available.
