[2][3] Stage one ("Premodern traditional society"): This is before the onset of urbanization, and involves little to no migration, while natural increase rates are about zero.
The high mortality of pre-modern societies compensates for higher fertility and slow population growth.
Internationally migration rates are high, although the total population number is still rising.
Mortality falls while population growth slows due to eroding social norms.
Stage five ("Future super-advanced society"): During stage five "Nearly all residential migration may be of the interurban and intraurban variety.... No plausible predictions of fertility behavior because of a declining population,...a stable mortality pattern slightly below present levels".
