Detailed explanation-1: -The third stage of demographic transition is characterised with low growth rate of population due to decline in both birth as well as the death rate.

Detailed explanation-2: -Stage 2 of the Demographic Transition Model (DTM) is characterized by a rapid decrease in a country’s death rate while the birth rate remains high. As such, the total population of a country in Stage 2 will rise because births outnumber deaths, not because the birth rate is rising.

Detailed explanation-3: -Stage three. In Stage 3 of the Demographic Transition Model (DTM), death rates are low and birth rates diminish, as a rule accordingly of enhanced economic conditions, an expansion in women’s status and education, and access to contraception.

Detailed explanation-4: -In Stage 3, birth rates gradually decrease, usually as a result of improved economic conditions, an increase in women’s status, and access to contraception. Population growth continues, but at a lower rate. Most developing countries are in Stage 3.

Detailed explanation-5: -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.
