Gallup said that 22 percent of the world's population live in the World Bank Group's definition of extreme poverty, which is less than $1.25 per day.
Slightly more than a third, 34 percent, live on less than $2 per day, Gallup said Monday. Further, in 86 countries, more than 3 percent of the population lives in extreme poverty.
In 27 African countries Gallup said "most" of the residents, 54 percent, live in extreme poverty.
The highest extreme poverty rates are in Burundi and Liberia, where the rate is nearly 90 percent. The top 10 poorest countries are all in sub-Saharan Africa and each of those countries has extreme poverty rates of more than 66 percent.
By contrast, across Australia, New Zealand, the United States, Canada and most of Europe, less than 1 percent live in extreme poverty.
Gallup said the results of the survey include a margin of error of as much as 4.7 percentage points.
