I don't know exact figures, but I'm absolutely certain that if you plotted the distribution of wages, you'd see a hugely disproportionate number at or just above the minimum wage. Y'know, because there's an artificial pressure (the law) preventing anyone from paying less.

Housing prices, meanwhile, are not subject to the same kinds of constraints. They likely follow a much more normal distribution (though not, I suspect, a normal distribution in the statistical sense).
