North Korea's declining birth rate casts a lengthening shadow over its economy, a trend that ties low fertility to shrinking labour pools and fading market demand—a correlation that demands scrutiny. The United Nation's "World Population Prospects 2024" paints a tame picture, pegging the country's birth rate as slipping gently from 2.17 in the 1990s to 1.86 in the 2010s, suggesting a manageable dip. Yet, this rosy view clashes with sharper evidence: research, including defector interviews by Lee and Kim, reveals a plunge from 1.91 to 1.38 over those decades, far steeper than UN estimates. This gap matters—South Korea's dream of a unification "population bonus" fizzles if North Korea's births don't outpace its southern twin, now at a mere 1.15. Drawing on defector testimonies, North Korean laws, and state media, the reality emerges: a demographic slide already gnawing at labour and markets.
The story starts in the 1990s with the Arduous March, a famine that gutted birth rates as women flocked to jangmadang markets, prioritising trade over family amid fierce competition. By the 2010s, this paid off—fewer kids, down to one or two per household, lifted living standards. Rice became a staple for 79 percent of homes by 2018-2020, up from 48 percent earlier in the decade, per Seoul National University's data; meat hit tables weekly for 58 percent, up from 34 percent. Clothing sales held steady as parents splurged on branded gear—defectors recall teens in "leaf-shaped" Adidas knockoffs—and housing space per adult grew 10 percent by 2017. But the tide turned mid-decade. The 1990s birth slump shrank the military-age pool by the late 2010s, forcing relaxed enlistment rules and a shift to conscription—women's service doubled from 5 percent (1970s births) to over 10 percent (1990s births).
Since 2020, the working-age population has shrunk nearly 1 percent yearly, per Lee and Kim, and the fallout's stark. Farms and mines bleed workers, prompting forced "volunteering" of youth and a push for married women—79,000 joined production sites in 2024, spurred by party edicts post-2023. Markets, meanwhile, stagnate as the 20s-30s crowd—vital for innovation and hustle—thins out, dragging aggregate demand down. NKID's 2024 sales estimates lag pre-Covid levels, with merchants turning to herb picking to scrape by. North Korea's response? The 2022 Childcare Act offers free dairy, the 2023 Housing Act favours big families, and late-2010s rules tied promotions to having kids. Yet, an aging population—14 percent over 65 by 2025—looms, threatening a vicious cycle: economic decay feeding demographic collapse, and vice versa.
Even a communist fortress like North Korea can't dodge this birth dearth, a plight shared with capitalist peers—a riddle rooted not in ideology but in modernity's grip. The Arduous March shoved women into markets, mirroring global urbanisation's pull; the 2010s saw material perks—better food, branded clothes—trump more mouths to feed, a choice as capitalist as it gets. Kim Jong Un's pleas at the 2023 Mothers' Conference for revolutionary baby-making fall flat against this tide—defectors show a chase for personal gain, not collective glory. Modernity's hallmarks—education, work, density—slash fertility everywhere: North Korean women, like South Korea's (0.75 rate) or Japan's, delay or ditch kids for stability, a pattern the 1990s famine locked in. Materialism cements it—fewer kids mean more per head, a lure no system upends.
No fix exists. Communist coercion—conscription, labour drives—patches holes but doesn't reverse the slide; capitalist bribes, like South Korea's $300 billion fertility flop, fare no better. Modernity's ethos—self over species—overrides both. North Korea's aging crisis apes Japan or Italy, not Mao's heyday, and its labour-heavy model just sharpens the sting. This isn't a policy puzzle; it's a trap of progress and want, grinding on unsolvable. Monitoring North Korea's demographics and Kim's flailing fixes won't change the maths—it just maps the inevitable of population decline, if not crash.
