LULC changes and urban expansion of Greater Dhaka is governed by a combination of geographical, environmental and
socio-economic factors. Although population growth is the primary cause for rapid urbanization, the contribution of other causes such as economic development and physical factors also needs to be assessed. To evaluate the mechanisms underlying the changes in LULC and subsequent urban expansion, we performed a regression analysis of built-up areas using selected physical and socio-economic variables (elevation, slope, population and GDP), and presented the results in Table 5. Urban area data were extracted from annual BBS statistics since RS data only cover three years. To examine the effects of slope and elevation on urban expansion, mean values of slope, and elevation of both developed and underdeveloped areas in the city were calculated from a digital elevation model. Socio-economic data, such as population and GDP values were obtained from the decadal and yearly annual tables of the Bangladesh Bureau of Statistics (Table 1)
