Chronic diseases are some of the most widespread and expensive health conditions in the United States. This study evaluates the prevalence of chronic diseases in the U.S. from 2011 to 2021, using data from the U.S. CDC, along with visualization and descriptive statistical analysis techniques. Despite increased awareness and advancements in prevention, diagnostics, and treatment, the prevalence of certain chronic diseases, such as obesity, diabetes, and asthma, continues to rise each year. Other conditions, such as kidney disease and heavy alcohol consumption, have shown little to no improvement. Notably, the prevalence of these diseases in each state is not directly correlated with population size but is instead influenced by various factors, including living conditions, unhealthy lifestyle habits, socioeconomic status, and access to healthcare services. For instance, Mississippi has an average obesity rate of 37.6% and an average diabetes rate of 12.8%, both of which are partially influenced by an average tobacco use rate of 23%. In comparison, the U.S. averages for obesity, diabetes, and tobacco use are 30.4%, 9.5%, and 18.3%, respectively.
