I am not a fan of their initial "Global Income Distribution" curve. if you take the actual data at the bottom of the article and plot it; it does not make anything the resembles a standard distribution as portrayed. It could be an infographic, it could be different axis, who knows, but portraying a standard distribution is wrong if you have an outlying skew in your distribution. Everything under $40 is a standard distribution, but above $40 represents the same volume of people as the average skewing any sort of plotting.

For 2025 only

Global People | Dollars

1,183,873,832 | above $40

389,144,677 | $30-$40

681,087,495 | $20-$30

1,647,364,177 | $10-$20

1,134,291,724 | $7-$10

1,170,170,455 | $5-$7

1,185,828,184 | $3-$5

700,440,541 | $1-$3

107,765,635 | <$1

The x-axis isn't "income", it's "log income".

It would be nice to see above 1000

I wish these numbers were percentile relative to the local economy and not in made-up "international dollars."

It means absolutely nothing that 1.1B people live on $3-5/day and a different 1.1B live on $5-7. Can you survive in the local economy on $2/day? Then $4/day is not that bad, and $7/day is doing pretty well.
