The median wage in the US per person is $26,695. This tells us a lot since the median household income is at $50,500. Since the Census data looks at households, this data hones in on individual wage earners. 66 percent of Americans earn less than $41,212.
Once they have the total wage bill for each country, they add them all together and divide by the total number of earners in the world. That gives you the answer - the world's average salary is $1,480 (Â£928) a month, which is just less than $18,000 (Â£11,291) a year.
