| Summary: | Worldwide increase in urban population draws special attention to urban population density related research. Based
on Thana level census data for the years 2001 and 2011, this study attempts to analyze the density gradient of urban
population in Dhaka Metropolitan Area using Geographic Information Systems (GIS). Four mathematical functions
have been considered to examine the change in population density with distance from CBD, after the classical work
of Colin Clark in 1951. The density gradient appears to be following the negative exponential function. Result
reveals that the density curve flattens over time, indicating greater increase of population density in the areas located
further from the CBD than areas adjacent to it. GIS-based surface modeling using density contours shows the spatial
pattern of population density has changed substantially. The study further corroborates that historical as well as
economic factors are influencing the pattern and change of population density in Dhaka Metropolitan Area (DMA). |
