Q
  1. Demographic Transistion
A

The process of change in a society’s population from a condition of high crude birth and death rates and low rate of natural increase to a condition of low crude birth and death rates, low rates of natural increase, and higher total population.

18
Q
  1. Medical Revolution

20
Q
  1. Epidemiological Transition
A

21
Q
  1. Epidemiology
A

The branch of medical science concerned with the incident, distribution, and control of diseases that are prevalent among a population at a special time and are produced by some special causes not generally present in the affected locality.

22
Q
  1. Pandemic

23
Q
  1. Infant Mortality Rate
A

(IMR) The total number of deaths in a year among infants under one year of age for every 1000 live births in a society.

24
