correct, 90% of people make more than $1.90 ppp according to the data. but only 35% make more than $10 a day.

the poverty line is defined generously at ~$2 / day by most oecd countries, but making above the poverty line does not make you not poor.

all of that said, the field of development economics has been very rich in research these days, particular from the likes of duflo and banerjee

The chart measurement is in constant PPP dollars and clearly shows a downtrend in all poverty worldwide over time. Obviously the line of what constitutes "poor" is debatable, but what's far more interesting is the continuing growth in people who are rich.
