To find out The Economist looked at how much the main breadwinner in an average household makes each year (before tax).
On this measure, USA creates the most millionaires (around 5m households, or 4% of the total). South of the border, Mexicans can expect to work for three centuries to earn the same.
For those struggling to imagine $1m, consider this: stacked up and denominated in $100 notes, it reaches over a meter high and weighs ten kilograms.
