Model Stages
Phase one (“Premodern traditional society”): This is before the onset of the urbanisation, and there is very little migration. Natural increase rates are about zero.
Phase two (“Early transitional society”): There is “massive movement from countryside to cities... as a community experiences the process of modernisation”. There is “rapid rate of natural increase”.
Phase three (“Late transitional society”): This phase corresponds to the “critical rung...of the mobility transition” where urban-to-urban migration surpasses the ruralto- urban migration, where rural-to-urban migration “continues but at waning absolute or relative rates”, and a “complex migrational and circulatory movements within the urban network, from city to city or within a single metropolitan region” increased, non-economic migration and circulation began to emerge.
Phase four (“Advanced society”): The “movement from countryside to city continues but is further reduced in absolute and relative terms, vigorous movement of migrants from city to city and within individual urban agglomerations...especially within a highly elaborated lattice of major and minor metropolises” is observed. There is “slight to moderate rate of natural increase or none at all”.
Phase five (“Future superadvanced society”): “Nearly all residential migration may be of the interurban and intraurban variety….No plausible predictions of fertility behaviour,...a stable mortality pattern slightly below present levels”.

Famous quotes containing the words model and/or stages:
“When you model yourself on people, you should try to resemble their good sides.”
—Molière [Jean Baptiste Poquelin] (16221673)
“But parents can be understanding and accept the more difficult stages as necessary times of growth for the child. Parents can appreciate the fact that these phases are not easy for the child to live through either; rapid growth times are hard on a child. Perhaps its a small comfort to know that the harder-to-live-with stages do alternate with the calmer times,so parents can count on getting periodic breaks.”
—Saf Lerman (20th century)
