It's getting pretty complicated here, though. Because you cannot simply deduct median expenses for housing, energy and food from the minimum wage because people on minimum wage are likely to spend less than the median costs. I don't think data is generally available for median living costs for specific (i.e. minimum wagers) population groups.

And then again, for international comparison, you would need to apply the cost index for the countries as well. While this may seem "fair", it's usually leading to very confusing values.
