I had the number of years wrong as I was relying on my terrible memory instead of looking it up before posting, that said, not sure where you are getting your numbers from since you didn’t post any links.
According to the World Bank global poverty was cut in half in 30 years, not 20 as I posted:
For 30 years, global extreme poverty had been steadily declining, and by 2015, the global extreme-poverty rate had been cut by more than half.
That’s from this link: https://www.worldbank.org/en/topic/poverty
While pre-pandemic global poverty rates had been cut by more than half since 2000,
That’s the first sentence from this article by the UN (the people you claim say poverty is increasing)
Politifact says that the claim:
“Over the last 30 years, extreme poverty has been cut in half.”
Is mostly true at this link: https://www.politifact.com/factchecks/2016/mar/23/gayle-smith/did-we-really-reduce-extreme-poverty-half-30-years/
If you look at the second graph on the wikipedia page on Extreme Poverty here: https://en.m.wikipedia.org/wiki/Extreme_poverty it looks like the total number of people in poverty was around 1.6 billion around the year 2000, but by 2015 it appears to have dropped below 800 million.
So yeah, it’s obvious that there’s a lot of variations in the numbers but still looks like my initial claim was not completely without merit.
What distribution are you on?
