Increased maternal death in the United States

While still relatively rare, maternal mortality in the United States increased over the years. In most other developed countries, rates decreased over the same time period. From NYT Opinion:

Over the past two decades, maternal mortality has increased almost 60 percent. The United States is the only other Group of 7 country besides Canada to experience such a drastic decline in maternal health. (Canada saw a minor increase in pregnancy-related deaths.)
