"GLOBAL ISSUES, LEADERSHIP CHOICES":

Demographics may not be destiny precisely, but their direction is difficult to change, especially in the short term. A recent article from Foreign Policy highlights key demographic trends shaping our future world. "What’s notable about these disparate trends is how much they are interrelated. They’re driven not just by the traditional demographic triad of births-deaths-and-migration, but by myriad powerful new forces that define modernity — from the empowerment of women, to improvements in health care, to the information and technology revolutions, to the concurrent rise of secularization and religious fundamentalism. However, the fact that they are connected does not mean they are universal. Beneath the broad umbrella of global demographic change, there will be sharp variances across regions (and sometimes within countries)." 

For example, by 2050, "the world’s fastest-growing region, Africa, is projected to see its population more than double, while the slowest-growing region, Europe, is expected to see its population decline by about 4 percent.  This means that in 2050 there will be around 3.5 times more Africans (2.5 billion) than Europeans (707 million). In 1950, there were nearly twice as many Europeans as Africans." features.foreignpolicy.com/heres-looking-at-you-2050-christianity-islam-aging-population/
