It hasn’t always been like this. In the 1960s, the United States actually had a lower infant mortality rate than the average among its peer countries. The country began to lag in the 1980s.
“Although U.S. infant mortality declined by 20 percent between 1990 and 2010,” the report notes, “other high-income countries experienced much steeper declines and halved their infant mortality rates over those two decades.”
As to what explains the high infant mortality rate, the researchers aren’t quite sure. They say it is not explained by ethnic diversity in the United States. While U.S. minorities do tend to have a higher infant mortality rate, non-Hispanic whites in the United States also have worse outcomes than those in peer nations.
