Here below you leave a copy of the article on the Greek theory of demographic transition, you also attach a chart which represents the process and a link to more information in case any of you need a little more about subject.
Description schematic timeless explains the process in which a company is subject, going from being dominated by a demographic regime based on mortality rates and birth to a new regime characterized by the reduction of these rates.
The transition theory is a logical situation established in three phases. The first phase, or pre-transitional period, is characterized by high birth rates and mortality and low life expectancy. In this period, which is called also old demographic regime or regimen traditional demographic, mortality and affects more children can appreciate subsistence crises caused by major famines, epidemics and wars, which graphite socioeconomic peaks recurring line mortality rates that occur above and birth rates are due to cyclical periods, where population growth is very low or almost zero. This phase describes the demographic development of the pre-industrial societies. The second socioeconomic phase is the one that calls itself demographic transition. In this period there is, first, a decrease in mortality rates that favors a subsequent decrease in birth rates. The gap between the different rates is due to the time that people need to adapt to the fact that mortality is actually lower. This mismatch causes a maximum population growth in much reduced mortality rates remain high and birth rates. This is what we called population explosion. The third phase or post-transitional period, also called the new demographic regime or modern demographic regime is characterized by low birth and death rates and high life expectancy. In this period the birth rate fluctuations shows alternatives in response socioeconomic to various economic situations. The theory of demographic transition has dominated thinking since its appearance. socioeconomic
This theory appeared as a simple vision states that the process of demographic change had occurred in industrialized countries today, throughout the nineteenth and twentieth centuries, although the timing of the transition is different for each region, as well as may be different from the duration of each stage. During the transition mortality is considered the engine of change -for the lower incidence of epidemic cycles and crises of subsistence, but the main factors that affect value are cultural, economic, political and social. On the one hand there is a greater literacy, there is a parallel to the industrialization process of planning another enabling further socioeconomic economic development, while we noted some improvements socioeconomic in health, hygiene and food; evolution of transport, communications and trade; and new cosmological visions, ie, a change of mentality, both in loss of power of religion, as in the new role of women in society, which leads to a restructuring of old schemes, such as family.
The desire -aparegut in the early seventies the historical scheme used to predict a new transition in developing countries has led to negative verdicts issued toward the same academic formulation of the theory of the transition, although this is not only raises studies in the field of demography, but in the same way it does so from the perspective of history, geography and sociology.
