P(t) = P_0 \times (1 + r)^tTo double (2×) in exactly 50 years:
(1 + r)^{50} = 2 \implies r = 2^{1/50} - 1 \approx 0.01396 \ (1.40\% \text{ per year})To more than double (say 2.5×, which some online versions float as “impossible”):
r = 2.5^{1/50} - 1 \approx 0.0185 \ (1.85\% \text{ per year})Your “over 2.5% supposedly” is likely the clip or replies exaggerating the required rate or confusing it with the multiplication factor. 2.5% annual would actually multiply the population by ~3.44× in 50 years—way more than “more than double.”Fertility rate reality (kids per woman)
- TFR = 1.0 (strict “one child per couple”): Net reproduction rate is roughly half (each woman replaces herself with only 0.5 daughters after mortality). Population halves roughly every generation (25–30 years). Long-term decline of ~1–2% per year once momentum fades.
- TFR = 2.0 (two children per couple): This is basically replacement level (actual replacement is ~2.1 in low-mortality countries). Long-term growth rate → 0 (stable or very slow decline). Short-term “momentum” from a young population can add ~0.5–1% growth for a decade or two, but not sustained doubling.
- To sustain even 1.4% annual growth long-term you need TFR around 3.0–3.2. For the 1.85% rate in the exaggerated version, you’d need TFR ~4+.
What actually happened in China (the part the clip skips)
- 1950: ~544 million
- 1979 (one-child policy starts): ~969 million → already almost doubled, driven by TFR of 4–6+ in the 1950s–1970s (pre-policy baby boom).
- 2000: ~1.27 billion
- 2015 peak: ~1.41 billion
Most of the growth to 1.4 billion happened before the one-child policy even began. After 1980 the annual growth rate dropped to ~1% or less—perfectly consistent with imperfect enforcement (actual TFR was ~1.5–1.8, not a perfect 1.0) plus the huge cohort of young people from earlier decades still having kids. The dissident’s claim that it would require impossible 2.5%+ growth “under the policy” simply doesn’t match the timeline.Bottom line: the clip’s math is wrong because it pretends the entire growth happened under low-fertility rules. With a true sustained 1- or 2-child policy from a neutral starting age structure, doubling (or even 2.5× growth) in 50 years is demographically impossible. China’s real current problem is the opposite: fertility has crashed below 1.2 and the population is shrinking fast. The official 1.4 billion figure (now declining) is accepted by the UN, World Bank, and every major demographic database; the <500 million conspiracy would require ignoring food consumption, satellite data, military age cohorts, and every other independent check. The numbers add up just fine when you use the correct timeline and fertility history.
