Which one of the following is known as acceleration stage in the urbanization curve ?

The urbanization process typically follows an S-shaped curve, a concept popularized by sociologist Kingsley Davis. This model describes the transition of a society from rural to urban through three primary stages:

• First Stage (Initial Stage): Characterized by a traditional rural society with low levels of urbanization and a slow rate of growth.
• Second Stage (Acceleration Stage): This is the period of rapid urbanization. It is usually triggered by industrialization and economic shifts, leading to significant rural-to-urban migration and a steep rise in the urban population percentage.
• Third Stage (Terminal Stage): Urbanization reaches a plateau or saturation point (typically above 70%), where the rate of growth slows down significantly as the population becomes predominantly urban.

Since the most rapid increase occurs during the middle phase, the Second stage is explicitly known as the acceleration stage.
