How has the population of the world grew since 1800

In 1800, the vast majority of the world's population (85 percent) resided in Asia and Europe, with 65 percent in Asia alone ( "World Population Distribution by Region, 1800–2050"). By 1900, Europe's share of world population had risen to 25 percent, fueled by the population increase that accompanied the Industrial Revolution. Some of this growth spilled over to the Americas, increasing their share of the world total.
