mortality is the fundamental factor in the dynamics of population growth and causes of death

Mortality is the fundamental factor in the dynamics of population growth and causes of death.

Mortality has no fixed upper limits. Thus if fertility approached its upper maximum, depopulation would still occur.

slide7
During the epidemiologic transition, a long-term shift occurs in mortality and disease patterns whereby pandemics of infection are replaced by degenerative and man-made diseases...
age of pestilence and famine

Age of Pestilence and Famine

Characterized by high mortality rates, wide swings in the mortality rate, little population growth and very low life expectancy

age of receding pandemics

Age of Receding Pandemics

Epidemics become less frequent, infectious diseases in general become less frequent, a slow rise in degenerative diseases begin to appear

slide10
The shifts in disease patterns in the 19th century were primarily related to changing SES.With the 20th Century more related with disease control activities independent of SES:e.g. Mexico, China
