FAST FIVE: Visualizing The World's Population At 8 Billion
Nigeria is Africa's most populous country and its largest economy.
On the other, are Middle Eastern nations like Oman and Qatar, which have robust population growth rates of 4-5%.
Russia remains Europe's largest country by population.
America's population is still growing modestly (by global standards), but perhaps more interesting are the internal migration patterns that are occurring.
In fact, Earth's population is expected to continue growing until it hits a peak at some point in the 2080s-possibly over the 10 billion mark.
