You realize that the latest global 2050 population estimates while being more or less unchanged in total (11B+), had an upward prediction for Africa as a direct consequence of the Trump administration's changes in support for birth control programs in the region?

This decision taken by the U.S. will have a major impact on Africa’s population issues, and policies will be needed to counter that."
