What is meant by ‘birth rate’ and ‘death rate’? Explain why the birth rate is relatively slow to fall while the death rate declines much faster.

Birth rate means the number of live births per thousand persons in a year, it is different from actual number of birth.

Death rate means the number of deaths per thousand persons in a year, it is different from actual number of deaths.

The birth rate falls slowly than death rate because controlling the birth rate is a socio-cultural phenomenon which is slow to change whereas the death rate can be controlled by public health measures and medical advancements.
