At times the exodus led to privation, misery and disappointment. Nevertheless, man being what he is, continued to move and shift seeking greener pastures, which he hoped to find in cities. Thus urbanization has become a way of life.
The urban society is a mix of multitudes of population. Size of settlement determines the character of the society. Social institutions and practices continue to exist not because they are needed anymore but because they are a part of life. It is a mix of heterogeneous culture and people with varied interests and variegated traditions. This cauldron gives gives birth to a new hybrid culture. Urbanism has developed one primary character. The close-knit rural society has given place to isolation. People to people contacts have become impersonal, superficial and transitory. Human relationship that developed here is need based.
According to Wirth city is a product of growth. A village due to extraneous and internal forces grows in population and in size. But Wirth is of the view that the basic characteristics of the society; cultural, traditional, and social will continue to be the same with small variations. So he says, there would be no discontinuity in the personality of the rural and the urban.
"Wirth suggests that those components of urbanization; size, density, heterogeneity are the independent variables that create a distinct way of life called urbanism".
