Just since 1990, more than 100 million children’s lives have been saved through vaccinations and improved nutrition and medical care. They’re no longer dying of malaria, diarrhea or unpleasant causes like having one’s intestines blocked by wriggling worms. (This is a good news column, but I didn’t say it wouldn’t be a bit gross.)

“There are deworming campaigns now, so it’s much rarer that we go into surgery for obstruction and see a big mass of worms,” explained Agatha Neufville, the nursing director at the Ganta United Methodist Hospital.

Nine out of 10 Americans say in polls that global poverty has been staying the same or worsening. So let’s correct the record.

There has been a stunning decline in extreme poverty, defined as less than about $2 per person per day, adjusted for inflation. For most of history, probably more than 90 percent of the world population lived in extreme poverty, plunging to fewer than 10 percent today.

Every day, another 250,000 people graduate from extreme poverty, according to World Bank figures. About 300,000 get electricity for the first time. Some 285,000 get their first access to clean drinking water. When I was a boy, a majority of adults had always been illiterate, but now more than 85 percent can read.

Family planning leads parents to have fewer babies and invest more in each. The number of global war deaths is far below what it was in the 1950s through the 1990s, let alone the murderous 1930s and ’40s.
