# Father of Health Statistics is:

# Father of Health Statistics is:
A. John Snow
B. John Graunt
C. Fredrick Mckay
D. Pierre Fauchard

Answer: B, John Graunt

Graunt, along with William Petty, developed early human statistical and census methods that later provided a framework for modern demography. He is credited with producing the first life table, giving probabilities of survival to each age. Graunt is also considered as one of the first experts in epidemiology, since his famous book was concerned mostly with public health statistics.
