Bangladesh Urbanization Overview 2020
In 2020, Bangladesh had an urban population of about 64.6 million, or 38.2% of the total population, and it has been increasing at an annual rate of 3.5%. The urbanization rate rose by 14.6 percentage points over twenty years, from 23.6% in 2000, and is expected to exceed 50% by 2035. With a 3.5% yearly pace, Bangladesh is among the fastest urbanizing economies in South Asia, moving ahead of India (34.9%) and Pakistan (36.7%).
The core of this trend is the polarization between Dhaka Metropolis (22 million) and Chittagong (5.3 million). Dhaka absorbs about 500,000 newcomers each year and is one of the fastest-growing megacities globally. With population density around 23,000 people per square kilometer, overcrowding is severe. Traffic congestion, insufficient wastewater services, housing shortages, and air pollution have become key urban constraints, which is why metro rail, flyovers, and new-town development are being deployed. This creates a strong practical pipeline for Korean firms in construction, environmental technology, and transportation.
Dhaka Megacity Status and Key Challenges
Dhaka Metropolitan area is one of the most densely populated urban areas in the world. Its administrative area is split between DSCC (South Dhaka) and DNCC (North Dhaka), while the greater metropolitan region under RAJUK authority hosts about 22 million people. The built-up area is about 300 km², roughly half of Seoul's 605 km², yet the population is more than double. Average daily commuting can take 2 to 3 hours, with estimated economic losses of 2 to 3% of annual GDP. Water access is 82%, while round-the-clock water supply remains below 20%, and sewerage coverage is only 25%.
| Item | Current Level | Required Level | Gap | Investment Need ($B) | Note |
|---|---|---|---|---|---|
| Public Transport | Bus 95% | Metro + BRT | System missing | 10 | MRT under construction |
| Water Supply | 82% service | 100% 24-hour | 18% plus quality | 3 | DWASA |
| Sewerage | 25% coverage | 80% treatment | 55% point gap | 5 | STP shortage |
| Waste | 50% collection | 100% + recycling | 50% point gap | 2 | DSCC·DNCC |
| Roads | 2,000 km | 5,000 km | 3,000 km | 8 | Including elevated expressway |
| Housing | 30% slum | 100% affordable housing | 70% gap | 15 | Public housing |
| Power | 99% access | Stable supply | Frequent outages | 5 | Distribution upgrades |
New-Town Development and Deconcentration Strategy
The Bangladesh government is advancing a decentralization strategy combining new-town development to reduce Dhaka's concentration pressure. Purbachal, at 6,227 acres east of Dhaka, is a flagship program designed to host up to 1 million residents and managed by RAJUK (Capital Development Authority). It is planned as a smart-city framework, explicitly drawing lessons from Korean models such as Sejong City and Pangyo. BSMSN, or the Mirsarai Special Model Satellite Town, is positioned as an industrial satellite town in the northern Chittagong region to rebalance growth across the country. In transport, MRT-6 became the starting point of Dhaka's mobility transformation after partial launch in 2022. The completion of the Padma Bridge that year strengthened regional links between Dhaka and the south, supporting broader market integration.
Urban Infrastructure Opportunities for Korean Companies
Bangladesh's urbanization continues quickly from 38.2% toward 50% by 2035, at a pace of 3.5% per year. Dhaka's 22 million megacity concentration and infrastructure deficits are generating cumulative demand of more than $40 billion. From metro rail and wastewater to waste management, smart city systems, and housing, Korean firms are well matched to this demand, and multilateral financing from ADB, WB, and JICA is expected to sustain long-term project flow. New-city development in Purbachal and BSMSN is central to this trajectory, and the emerging urban demand remains one of Bangladesh's most reliable long-term growth engines.
