That’s the headline I’m reading here. Seems Europeans have been gaining on us, to the point where Americans are now shorter than the average Dutchman. From the article:
Researchers have established in recent years that wealthier families tend to provide better nutrition for their children and, as a result, they tend to grow taller. The drastic differences in the United States between rich and poor, the researchers pointed out, mean that the US average is pulled down by those who struggle to get by. Whereas in the US, some 15 percent of the population has no health insurance and those on welfare can barely get by, almost all citizens of northern and western European countries enjoy universal health care and a generous social net. The result is that even those children dependent on welfare in Europe have a sufficient living standard, the researchers concluded.
The downward trend started right around the time Reagan was president. It’s been pretty much all downhill from then.
