what is stage 1 of the DTM?
AGE OF PESTILENCE AND FAMINE
mortality is high and fluctuates, low/variable life expectancy
what is stage 2 of the DTM?
AGE OF RECEDING PANDEMICS
rate of mortality decreases, av. life expectancy increases, pop. growth is sustained and rises exponentially
what is stage 3 of the DTM?
AGE OF DEGENERATIVE AND MAN-MADE DISEASES
mortality continues to decrease and eventually approaches stability at a relatively low level, av. life expectancy inreases
what is stage 4 of the DTM?
AGE OF DELAYED DEGENERATIVE DISEASES
declining death rates concentrated at advanced ages, life expectancy increases
