 # In a demographic cycle, if death rate is declining but there is no increase in birth rate, this population is called as:

A. Early expanding

B. Low stationary

C. High stationary

D. Declining

The correct answer is A. Early expanding.

There is a demographic cycle of 5 stages through which a nation passes.

First stage (High stationary): This stage is characterized by a high birth rate and high death rate which cancel each other and the population remains stationary. 

Second stage (Early expanding): The death rate begins to decline while the birth rate remains unchanged. As the birth rates remain high, the population starts to grow rapidly.

Third stage (Late expanding)- Death rate declines still further and birth rate tends to fall, but population tends to grow as birth rate supersedes the death rates, but rates of population growth decelerates.

Fourth stage (Low stationary)- This stage is characterized by low birth and low death rate with the result that the population becomes stationary. Most industrialized countries have gone through a demographic transition from a high birth and high death rates to low birth and low death rates.

Fifth stage (Declining): Population begins to decline because birth rate is lower than death rate.
