Who is called the Father of Vital Statistics?

• A. Hippocrates
• B. John Graunt
• C. William Farr
• D. Edward Jenner

Answer: (C)

Vital statistics come from systematically collecting and analyzing data on births, deaths, and causes of death to inform public health decisions. William Farr is regarded as the father of vital statistics because he built and standardized national systems for recording vital events through the Registrar General’s Office, created uniform forms for births and deaths, and developed methods to classify causes of death and compute mortality rates by age, sex, place, and occupation. His work turned raw registration data into actionable health information, shaping sanitation reforms and health policy.

By contrast, John Graunt did early population statistics with Bills of Mortality and life tables, but Farr’s work established the modern, organized practice of vital statistics in a national public health context. Hippocrates and Edward Jenner contributed in other areas of medicine—humane health reasoning and vaccination, respectively—but not to the development of vital statistics systems.
