The urbanization as a concept, its dimensions and factors have always attracted the interest of many researchers across the globe. The present study aims to study the history of urbanization, urbanization concepts, its dimensions and factors like urban places, urban hierarchy, urban primacy, over-urbanization, urban sprawl, urbanism as a way of life, and factors of urbanization. After the comprehensive literature survey, results of various studies were correlated in a systematic manner for further analyses to reveal the findings and draw conclusions. The findings clearly depict that urbanized societies, in which a majority of the people live crowded together in towns and cities, represent a new and fundamental step in man’s social evolution. The way cities have influenced and shaped social life throughout the history has led the scholars of urban studies to delve into the origin and development of the urban form. Urbanization is a very complex phenomenon, with myraid dimensions. However, size of the place has been the most widely used criteria in the definition of urban population. Urban areas have a higher concentration of population in a limited area and thus a higher density of population and social heterogeneity.
