Satellite imaging has shown population increases are 10x higher in flood prone areas than previously thought, and a new way to introduce fairness into a democratic process. In this episode:00:47 Calculating how many people are at risk of floods.Researchers have used satellite imagery to estimate the number of people living in flood-prone regions. They suggest that the percentage of people exposed to floods has increased 10 times more than previously thought, and with climate change that number is only set to climb.

But deciding who is in these groups is a mathematical challenge — the process needs to be random, but still reflect social demographics. This week, researchers describe a new algorithm that could offer a solution.
