The time needed to get $1 in international dollars is 63 minutes in the US. This is about twice the average in Germany, France and the UK according to an Oxford University researcher. This suggests that average poverty is significantly higher in the US.
While this metric seems like a big win to evaluate poverty, it does not behave very well mathematically. Nobody makes infinite money/wealth, which makes wealth per day a stable metric. However, if someone makes very close to 0 wealth, the day per wealth metric will explode to infinity. One single individual can skew the day per wealth metric.
Other lemmees suggested to use the median. Or you can also try to incorporate the living cost by dividing the income by the cost of living. Maybe looking into quartiles or mean less multiples of standard deviation? Idk
Easily fixed by defining wealth as wealth + 1.
