Demographic transition is a model used to describe the basic characteristics of countries’ population changes, and it consists of several stages. In the first stage, birth and mortality rates are high, which produces low population growth. In the second (truly transitional) stage, a reduction in mortality and a continuing high birth rate lead to an increase in population growth rates. In the third phase, known as advanced transition, mortality rates have fallen and birth rates decline too, which results in increasingly lower rates of population growth. In the post-transition phase, birth rates drop below the level of mortality rates, thus resulting in extremely low or even negative natural population growth (Chackiel, 2004; Schkolnik, 2007; Villa and González, 2004).
