Who are the 10,000?

About 10,000 people eligible to vote, did not vote in last month's general election. Both parties are doing their analyses as to who these 10,000 voters are.

Many are simplistically saying that they must be disgruntled Nationalists. It would be interesting for us common citizens to know if this is true. I actually know a few Labourites who did not vote in the last general election. Surely, my sample is not representative and that is why I am asking the parties to give us the answer.
