Deceased (2009)
In 1820, more than 80% of the world's population lived in extreme poverty. By 2019, that figure had fallen to 8.9% at the then-$2.15/day line—a decline of roughly 0.35 percentage points per year sustained across two centuries. In June 2025, the World Bank adopted 2021 purchasing power parities (PPPs), raising the extreme poverty line to $3.00/day; this revised the 2022 rate upward to 10.5% (838 million people) but projects a decline to 9.9% (808 million) by 2025, continuing the historic trend through post-pandemic recovery.

In 1900, 41 percent of Americans worked on farms. Today, fewer than 2 percent do—yet agricultural output has more than tripled. The tractor, combine harvester, and chemical fertilizer didn't just change farming; they triggered the largest peacetime migration in American history, sending tens of millions from fields to factories and reshaping the nation's economy, culture, and landscape.

Died 2009
In the 1920s, natural disasters killed an average of 500,000 people per year. Today, with four times the global population, that number has dropped to roughly 45,000—a 99% decline in the per-capita death rate. The transformation happened not through divine intervention or luck, but through a century of investment in weather satellites, building codes, early warning networks, and agricultural science that turned existential threats into manageable emergencies.
