Martin Lewis wants more attention paid to it:
I find it extraordinary that the massive global drop in human fertility has been so little noticed by the media, escaping the attention of even highly educated Americans. The outdated idea that Mexico has a crushingly high birthrate continues to inform many discussions of immigration reform in the United States, even though Mexico’s TFR (2.32 in 2010) is only slightly above that of the United States.
It almost seems as though we have collectively decided to ignore this momentous transformation of human behavior.
Scholars and journalists alike continue to warn that global population is spiraling out of control. A recent LiveScience article, for example, quotes a co-author of an April 2013 Science report who argues that “the poorest nations are caught in a downward spiral that will deplete resources and cause a population explosion.” The article goes on to argue that “with the world population slated to hit 9 billion by the year 2050, many scientists and others worry that unchecked population growth and increasing consumption of natural resources will cause dire problems in the future.”
Although the LiveScience article notes that the original report focused on sub-Saharan Africa, it does not mention the fact that high birthrates are in fact increasingly confined to that part of the world, or that fertility rates are persistently declining in almost every country in Africa, albeit slowly. Many African states, moreover, are still sparsely settled and can accommodate significantly larger populations. The Central African Republic, for example, has a population of less than 4.5 million in an area almost the size of France.
