Health statistics are numerical data that help us understand the health of a population. They can include information about diseases, life expectancy, and the effectiveness of treatments. For example, CDC (Centers for Disease Control and Prevention) collects data on how many people are affected by illnesses like diabetes or heart disease. This information is crucial for public health officials to make informed decisions. These statistics are also used to track trends over time, such as the rise or fall of certain health issues. By analyzing health statistics, researchers can identify risk factors and develop strategies to improve overall community health.
