Bangladesh is a predominantly rural country which is recently going to get the status of a developing country has experienced remarkable urban growth over the last few decades. It is the 10th largest country in the world in terms of population density where 34.05% of the population live in urban areas. The study has explored the spatial distribution patterns in urbanization using the 64 administrative districts as the spatial unit of analysis. Different attributes of the spatial features namely level of urbanization, population density, and urban population density have been studied. Some spatial statistical tools and methods namely Nearest Neighbor Analysis, Spatial Autocorrelation, Moran’s I, General G-Statistics and Local Indicators of Spatial Association (LISA) have been used in this study. Analysis has been done using ArcGIS. The study found that urbanization and density in different districts follow cluster pattern though the distribution of the districts follows the dispersed pattern. In all cases, the capital city Dhaka is a hot spot while in some cases Chittagong and Narayanganj are the hot spot for urbanization and density in Bangladesh. Again, Dhaka with its neighboring districts namely Gazipur, Narsingdi, Narayanganj, and Munshiganj show high-high clustering whereas Chittagong is high outlier and Khulna regions shows low-low clustering in some cases. Some practical measures should be taken to ensure the balance urbanization throughout the country. One of these potential measures can be decentralization of Dhaka with providing different facilities and employment opportunities those are responsible for rapid urbanization.
