Health Factors

Health factors in the County Health Rankings represent what influences the health of a county. We measure four types of health factors: health behaviors, clinical care, social and economic, and physical environment factors. In turn, each of these factors is based on several measures. A fifth set of factors that influence health (genetics and biology) is not included in the Rankings.
