Extreme poverty, according to the WB, is a situation in which a person lives on an income of less than $1.90 per day. In other words, we're talking about real, grinding poverty, and not a lifestyle at the poverty line in America where the poor have cell phones and air conditioning. In other words, this measure of poverty isn't a relative measure, as is often used by the UN for measures such as its child poverty report.
According to the Bank:
The World Bank projects that global poverty will have fallen from 902 million people or 12.8 per cent of the global population in 2012 to 702 million people, or 9.6 per cent of the global population, this year.
We must note that richest countries of the world have already eradicated extreme poverty. There are not people who live on $1.90 in the US, Canada, Australia, or Western Europe. These countries simply do not contain more than a negligible number of people who live in mud huts, walk miles a day to get clean water, and have no access to modern health care. Even in Eastern Europe, where Soviet-style socialism persisted into the 1990s, we rarely find a population with more than 1 percent of the population that endured extreme poverty levels.
So, we look to Latin America, Asia, and Africa to find the populations that continue to endure under conditions of extreme poverty.
All data is from the World Bank and reflects data collected over the twenty years from 1992 to 2012, the last year that data is published. Worldwide during that period, extreme poverty fell from 34.7 percent to 12.7 percent.
Latin America is the least poor of the regions outside the wealthy west and Eastern Europe. The largest countries in Latin America have all been well below the worldwide rates for extreme poverty over the past twenty years:
In addition to seeing that Latin America has lower poverty in general than the world overall, we also can note that there has been substantial improvement in the twenty-year period. In Mexico during this period, extreme poverty dropped from 9.7 percent to 2.7 percent. Extreme poverty dropped even further in Brazil where the rate fell from 20.8 percent to 4.9 percent. In Columbia, the drop was smaller, but remained on the right track, with extreme poverty dropping from 8 percent to 6 percent.
Conditions are considerably worse in southern Asia and southeast Asia where extreme poverty rates exceeding 40 percent can be found. Nevertheless, in these cases we also find profound improvement over the 20 year period. In China, for example, extreme poverty fell from 57 percent to 11 percent. In Indonesia, the rate fell from 57 percent to 15 percent. Some of the least amount of progress was found in Bangladesh. But even , there, extreme poverty dropped by 20 percentage points from 63 percent to 43 percent.
The worst situation, however, was found in Africa where overall extreme poverty rates were higher, and the least amount of improvement was seen.
Among the largest countries in Africa, we find that extreme poverty continues to plague large portions of the population, although significant improvement was experienced in South Africa and Ethiopia. In Ethiopia, from 1992 to 2012, extreme poverty dropped from 67 percent to 33 percent, and it fell from 32 percent to 17 percent in South Africa.
