Health statistics are numbers that summarize information related to health. Researchers and experts from government, private, and non-profit agencies and organizations collect health statistics. They use the statistics to learn about public health and health care. Some of the types of statistics include:

• How many people in the country have a disease or how many people got the disease within a certain period of time
• How many people of a certain group have a disease. The groups could be based on location, race, ethnic group, sex, age, profession, income level, or level of education. This can help identify health disparities.
• Whether a treatment is safe and effective
• How many people were born and died. These are known as vital statistics.
• How many people have access to and use health care
• The quality and efficiency of our health care system
• Health care costs, including how much the government, employers, and individuals pay for health care. It could include how poor health can affect the country economically
• The impact of government programs and policies on health
• Risk factors for different diseases. An example would be how air pollution can raise your risk of lung diseases
• Ways to lower risk for diseases, such as exercise and weight loss to lower the risk of getting type 2 diabetes
