The hacked date on Ashley Madison revealed that 90 per cent to 95 per cent of Ashley Madison users were male. That's a lot of husbands! To visualise Ashley Madison's gender disparity across the world, Malfideleco drew a line in the sand of 85 per cent male users and plotted out which cities and countries have more male users than that and which places have less male users than that.
It's not exactly necessary to draw conclusions on these stats (or even, like, possible) -- more male users doesn't necessarily mean unhappy husbands, more female doesn't have to mean more unhappy wives -- but it's a little interesting to see how the countries and even continents are grouped similarly.
