What is included in vital statistics?

Vital statistics encompass data that reflects the health status of a population and includes key health indicators that can inform public health policies and research. The correct answer highlights vital signs, which are critical measurements such as pulse, blood pressure, oxygen saturation levels, and body temperature. These measurements provide immediate insight into a person's physiological state and are essential for medical assessments, especially in emergencies.

Patient medical history, medication records, and reports of prior surgeries pertain more specifically to an individual's medical file and detail their treatment and health background rather than presenting statistical data for broader health analysis. These records are useful for patient care but do not fall under the umbrella of vital statistics, which focus on generalized health metrics pertinent to populations or demographic studies.
