Forecast World Population Change — A Very Diverse Landscape

While the world is forecast to increase its population by 10.6 percent in the coming decade (749 million new people), that does not apply everywhere. Just 83.3 percent (191 out of 228) of all countries are forecast by the U.S. Census Bureau to increase in population from 2013 to 2023. Within the other five out of six countries, growth is expected to vary significantly.

Percentage wise, the top-20 countries are anticipated to increase in the next 10 years from 27.8 to 42.5 percent (with an average increase for the group of 31.2 percent). Try to imagine the impact on all forms of infrastructure by such a massive rate of growth. These countries are predominately located in the African and Middle East region. The high-growth rate countries, however, currently have just 7.6 percent of the world population, and will increase in the decade by less than 170 million.

The 20 countries with the largest expected percentage population decline are predominantly clustered among former Soviet Block members and smaller tropical islands. This group currently has as estimated 123.1 million inhabitants, but ranges in size from 5,774 people (the Cook Islands) to 44.6 million (Ukraine).

The 20 countries with the greatest expected number of new inhabitants currently make up two-thirds of the total world population (4.76 million people) and are expected to grow in the decade by 529.7 million and account for 70.6 percent of the population increase. This group of countries is widely distributed across the globe.

And where are the expected greatest numbers of population decline anticipated? While many former Soviet Block countries are included, the population loss group spans globally. Japan with an expected drop 2.95 million people in the coming 10 years ranks the largest decline, followed closely by the Ukraine.
