0 to 64 year old Global Population
The 0 to 64 year old global population is about 7 billion persons, as of 2018. The chart below shows the distribution and changing size of that population from 1950 through 2050 by high income (black line…$12,000+ income per capita including the US/Canada, most of Europe, Japan, Aus/NZ, etc.), upper middle (yellow line…$12,000 to $4,000 per capita income including China, Russia, Brazil, Turkey, Mexico, Thailand, Columbia, etc.), lower middle (red line…$4,000 to $1,000 per capita income including India, Indonesia, Pakistan, Bangladesh, Ukraine, Philippines, Egypt, etc.), and low income nations (blue line…less than $1,000 in per capita income including most of sub-Saharan Africa, Afghanistan, Haiti, etc.). The simple takeaway should be that the 0 to 64 year old populations among the high and upper middle income countries have ceased growing and will now be shrinking, indefinitely. All 0-64 year old population growth from now forward will be among the lower middle and low income nations of the world. So what?
