In this last stage both the birth rate and the death rate are low, so the population grows very slowly or stays almost steady.

It is the deepest landlocked and well-protected port on India's east coast. Visakhapatnam port in Andhra Pradesh lies in a natural harbour cut into the land, sheltered by the Dolphin's Nose headland, which protects ships from the waves of the Bay of Bengal.
