Dhaka's Position as a Global Megacity

Dhaka, Bangladesh is unequivocally a megacity — an urban agglomeration exceeding 10 million people — and ranks among the world's largest, fastest-growing, and most challenged.

Megacity Recognition by Major Institutions

Organization	Classification / Ranking	Key Metric
UN (World Urbanization Prospects)	Megacity (since ~2000)	Urban agglomeration >10M
Demographia (World Urban Areas)	#4–6 globally (varies by year)	Built-up area population ~22–23M
GaWC (Globalization & World Cities)	Beta+	Important regional hub, some global links
Oxford Global Metro Monitor	Top 30 metro GDP	GDP, employment, productivity growth
Brookings Institution	Featured in Global Metro research	Urbanization, governance, resilience
World Bank	Flagship megacity case study	Urban development, infrastructure, climate

Key Statistics (2023–2024)

City Corporation area: ~306 km²; ~10–11M
Greater Dhaka (metro): ~3,600 km²; 22–24M
Density: ~30,000/km² (city) — among world's highest
Growth rate: ~3.5%/yr (one of fastest)
GDP (metro): ~$160B (PPP ~$400B) — ~35% of Bangladesh GDP
Per capita GDP: ~$7,000 (PPP) — rising fast

Megacity Challenges

Air quality: Seasonal "severe" (AQI 200–300+); brick kilns, vehicles, dust

Housing: 30–40% in slums/informal settlements; vertical growth accelerating

Governance: Two city corporations (North/South); RAJUK planning; coordination gaps

Climate risk: Sea-level rise, subsidence, cyclones, heat stress — high vulnerability

Challenge	Status
Traffic congestion	World's worst (TomTom, INRIX); avg speed 7 km/h peak
Public transit	Metro Rail (MRT Line 6 open 2023; Lines 1, 5, 6 building); BRT planned
Waterlogging / floods	Annual monsoon paralysis; poor drainage, encroached canals

Megacity Opportunities

Demographic dividend: Young workforce (median age ~27)
Garment hub: #2 global apparel exporter ($45B+); 4M workers (mostly women)
Digital economy: Fintech (bKash, Nagad), e-commerce, startup ecosystem
Infrastructure pipeline: Metro, elevated expressway, Padma Bridge (opened 2022), airport expansion
Regional gateway: BBIN (Bangladesh-Bhutan-India-Nepal) corridor; Bay of Bengal hub

Dhaka is a megacity of extremes — immense density, growth, and challenge, but also energy, entrepreneurship, and strategic weight. Its trajectory will shape Bangladesh and South Asia.
