**Title:** How Societies Choose

**Abstract:** How can we measure a healthy democracy? There are infinitely many election systems -- how voters fill out a ballot and then how we combine ballots to decide the outcome -- and they all have different properties and tendencies. I will give some philosophical and some mathematical perspectives on finding fairness in representative democracy.
