Demographic transition model Demographic transition model was first developed in 1929 by Warren Thompson. Based on data from the period 1908-1927, mds collections there are three kinds of patterns of population growth, namely: Group A, the countries of Western Europe, Northern Europe and the U.S. are experiencing natural growth changes very high to very low growth in Group B, the countries Italy, mds collections Spain and the "Slavic" in Central Europe which experienced a decline in births and deaths, but the decline in mortality mds collections is the same or faster than birth. This condition is experienced by the country mds collections group A at 30 to 40 years earlier. Group C, the other countries that births and deaths has not changed, that is still very high. Frank Noteisten (1945) gives an account mds collections of the third pattern. For group A, was named the "incipient decline", group B is a "transitional growth", and group C is "high growth potential". Currently, the term demographic transition (demographic transition) is introduced. mds collections This transition is a process of reduction in mortality and fertility of a population from a high level to the low level, or of "high growth potential" to the "incipient decline". The transitions are given in the following figure: Stages mds collections of demographic transition Phase I. (High Growth Potential) Marked with high fertility and mortality reply. Natural growth mds collections dropped even lower (minus). Phase II. (Transitional Growth) Marked mds collections with decreased mortality faster than fertility, as a result mds collections of high population growth. Phase III. (Incipient Decline) Marked with low fertility and mortality and that population growth is also low. Criticism of the Demographic transition theory description is still rough, like, that high population growth is not only due to the reduction in mortality, but also the increase in fertility. The time required for each stage varies greatly between mds collections countries, therefore mds collections this theory is weak enough to be generalized. After fertility and mortality are at a very low rate, the next stage is likely that number will go up. Thus the actual transition phase can still be developed further. (Luky PRADITA/3609100020)
