1. Zelinsky Model ofMobility Transition• Closely resembles Demographic Transition Model• Check out the relationship between population growth and population migration
2. Phase one (“Premodern traditional society”): This is before the onsetof the urbanisation, and there is very little migration. Natural increaserates are about zero.Phase two (“Early transitional society”): There is “massivemovement from countryside to cities... as a community experiencesthe process of modernisation”. There is “rapid rate of naturalincrease”.Phase three (“Late transitional society”): This phase corresponds tothe “critical rung...of the mobility transition” where urban-to-urbanmigration 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 theurban network, from city to city or within a single metropolitanregion” increased, non-economic migration and circulation began toemerge.
3. Phase four (“Advanced society”): The “movement from countrysideto city continues but is further reduced in absolute and relativeterms, vigorous movement of migrants from city to city and withinindividual urban agglomerations...especially within a highlyelaborated 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 residentialmigration may be of the interurban and intraurban variety….Noplausible predictions of fertility behaviour,...a stable mortalitypattern slightly below present levels”.
