* Define demographic transition.
* Describe the 4 phases of demographic transition, including if the population is stable, growing, or declining in each. · * According to demographers, what factors lead to a decline in the crude birth rates (CBR) and crude death rates (CDR) in the epidemiologic and fertility phases of the demographic transition? · * Briefly describe three living conditions and/or environmental impacts in developed countries that have reached phase IV, and contrast them with these conditions or impacts in developing countries that remain in earlier phases. · * Assuming that the demographic transition phase IV is a goal for developing countries, what two programs or initiatives would you suggest to assist them in progress toward this goal?
The demographic transition is a theory that sought to explain demographic, originally, the relationship between demographic change and socio-economic changes that took place in the eighteenth century in the developed countries of Europe and thus the relationship between population, development and population growth. The demographic transition explain the shift from a preindustrial demographic regime, leaded by head rates of mortality and birth to another industry with strong population growth and subsequently postindustrial, with very low rates of death and birth. There are four phases of demographic transition:
1. The first stage, typical of pre-industrial societies, birth rates and death rates are too high, so the natural increase of the population is slow. This stage is the one that marked the history of humanity from its origins to the eighteenth century. In the Middle Ages and the Modern ages birth and mortality rates were close to 50%. In this phase, many children were born while at the same time. Mortality was very high even in years of ordinary life by the insecurity, poor nutrition, hygiene, sanitation, etc. Even more in the years of catastrophic mortality caused by war,...
