Beijing's Population: 21.9 Million (2020 Census) — A Megacity Managing Growth

According to China's 2020 Census (National Bureau of Statistics), Beijing's permanent resident population reached 21,893,095 — making it one of the world's largest capital cities and China's second-most populous city after Shanghai (~24.9M).

Growth Trajectory

Growth slowing due to population caps (23M target for 2035) and decentralization policies.

Demographic Structure

• Migrant population: ~7.5M (34%) — non-hukou residents driving growth
• Age: Median ~38; aging faster than national average (low fertility: ~0.7 TFR)
• Education: 40%+ college degree (highest among Chinese cities)
• Distribution: 16 districts; Chaoyang (3.9M), Haidian (3.8M) largest

Management Strategies

• Population caps: 23M by 2035 (2017–2035 Master Plan)
• Function decentralization: Non-capital functions → Tongzhou (sub-center), Xiongan New Area (Hebei), Beijing Daxing
• Hukou reform: Points-based settlement for migrants
• Industrial relocation: Low-end manufacturing/logistics moved out

Implications

• Density: 1,300/km² (but highly concentrated in 15% of land area)
• Transport: World's largest metro (800+ km), still expanding
• Housing: Prices among world's highest (income multiple >40×)
• Environment: Air quality improved (PM2.5 ↓50% since 2013), water scarcity persistent

Beijing manages megacity scale with authoritarian planning tools unavailable to democratic peers—successes in air quality, transit; challenges in affordability, aging, and sustainable carrying capacity.
