Urban Spatial Growth: the Case of Bangladesh M. Shahidul Islam Research Fellow, Institute of Governance Studies, BRAC University Mohammad Nasir Uddin khan Senior Research Associate, Research and Evaluation Division, BRAC Spatial concentration of economic activities, fundamental forces • Urban economists define a city as a spatial concentration of economic activities. • Key determinants of spatial structure of economic activity: low transport costs and increasing returns to scale in production. • Rather than growing in parallel, regions /cities have a tendency to grow in sequence – the phenomenon is widely captured in cross country studies; • Out of 858 Chinese cities, 14 generate 33 percent of China’s GDP (Mckinsey, 2011); Urbanisation and unbalanced growth: theory and literature • Factors influence unbalanced or lumpy growth: history, location, migration, economies of scale/agglomeration economics, range of preference grants by central government (EPZ, for instance), market access, quality of public service, and urban bias; • Theoretical explanations of unbalanced growth: the existence of increasing returns to scale - New Economic Geography developed (Krugman, 1991): the importance of locational fundamentals; - physical landscape, such as temperature, rainfall, access to the sea, the presence of natural resources. The case of Bangladesh • Urban growth in Bangladesh is apparently following a similar trend that economic mountains are concentrated in few places; The big picture: Bangladesh and its immediate neighbourhood at night (the brightest areas of the Earth are the most urbanized, but not necessarily the most populated) Rationale and methodology of the study • Rationale: Policy bias, high opportunity cost of scarce resources • Methodology: • Definition of urban area: • Population Census 2001: Four distinct classes on the basis of their functions and sizes: megacity, statistical metropolitan area (SMA), municipality area and other urban area; • Bangladesh Population & Housing Census 2011: urban area corresponds: metalled roads, improved communication, electricity, gas, water supply, sewerage, sanitation and also having comparatively higher density of population with majority population in non-agricultural occupations. • Urban areas are classified into three categories: • City Corporation; Paurashava/Municipality Area; Other Urban Area The settlement pattern of urban population in Bangladesh and other developing countries Identification of top urban districts • We indentify the following variables that could explain trends, pattern and differences of urbanisation in various districts in 64 districts of Bangladesh: • Share of urban population in total population (r_shareup) • Population density (r_dens) • Share of immigrants in total population (r_immper) • Size of urban population (r_popsz) • Area (r_area) • Per capita GDP (r_percgdp) • Off-farm per capita income (r_ofpercapy) • Manufacturing share in GDP (r_mamugdp) • Total number of manufacturing and services establishments (r_alsecamnt) • Total unit of manufacturing establishments (r_manuamnt) • Employment in total establishments (r_alsecemp) • Employment in manufacturing establishments (r_manuemp) Data Source: Population Census 2001, BBS and Economic Census 2003, BBS.

Dhaka’s primacy East-West divide remains, but some districts in the West are catching-up Urabanization in Bangladesh, 2011 PANCHAGARH THAKURGAON NILPHAMARILALMONIRHAT KURIGRAM ¯ DINAJPUR RANGPUR INDIA GAIBANDHA SHERPUR JOYPURHAT NAOGAON SUNAMGANJ SYLHET NETRAKONA BOGRA JAMALPUR NAWABGANJ MYMENSINGH RAJSHAHI MOULVI BAZAR SIRAJGANJ NATOR TANGAIL KISHOREGANJ HABIGANJ GAZIPUR INDIA PABNA NARSINGDI BRAHMANBARIA KUSHTIA MEHERPUR MANIKGANJ DHAKA INDIA RAJBARI NARAYANGANJ CHUADANGA JHENAIDAH FARIDPUR MUNSHIGANJ COMILLA MAGURA SHARIATPURCHANDPUR NARAIL MADARIPUR KHAGRACHHARI JESSORE GOPALGANJ FENI LAKSHMIPUR BARISAL NOAKHALI RANGAMATI KHULNA PIROJPUR BAGERHATJHALAKATI SATKHIRA BHOLA CHITTAGONG PATUAKHALI BARGUNA BANDARBAN Legend COX'S BAZAR urbanization BAY OF BENGAL Study_Area Least urban 33 Solid urban: 5 Upcoming 20 Other urban 6 • Dhaka-Chittagong urban corridor • Chittagong: first urban district? Conclusions •There is a high correlation between industry and service establishments and level of urbanisation. -Thus, urbanisation in top districts is probably largely due to pull factors • Location is also a strong determinant of urbanisation. • While dominance of a few districts are overwhelming, a large number of districts – mostly located in Dhaka and Chittagong- are experiencing fast unbanisation • Districts that experienced rapid population growth between 2001-2011 are not the traditional ones (other than Big 5); They have approx. 96 lac (9.6 million) urban population; thus there is a growing consumer market beyond the Big-5. Conclusions • A number of districts in other divisions, apart from regional urban hubs (Rajshahi, Khulna and Rangpur) are undergoing significant urbanisation. • Border districts fare well in the country’s urban map- of 31 urban districts 14 share border with neighbours (mostly India) and of them at least 9 have active border trade. • Dhaka-Chittagong Urban corridor are connecting districts that were separated geographically a decade ago; • Nearly 50 lac (4.7 million) new urban population added between 2001-2011: - Dhaka, Bogra, Sylhet, Comilla, Noakhali and Cox’s Bazar absorbed 3.2 million population Border districts .
