Detailed explanation-1: -Birth Rate remains high. Death Rate is falling. Population begins to rise steadily.
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: -Example: poorest developing countries like Afghanistan, Pakistan, Bolivia, sub-Saharan countries such as Niger, Uganda and middle east countries like Yemen, Palestinian Territories are still in stage 2.
Detailed explanation-4: -In stage two, that of a developing country, the death rates drop quickly due to improvements in food supply and sanitation, which increase life expectancy and reduce disease.
Detailed explanation-5: -Stage 2: This is when the death rate falls rapidly. The birth rate remains high. Total population will start to rise because the death rates will start to fall (to around 18/19 per 1, 000).
