This thesis explores the factors that impact healthcare spending, such as economic conditions, demographic shifts, the structure of healthcare systems, and behavioral influences. It features a theoretical overview and a practical analysis using Power BI to uncover patterns and relationships within the data. The main areas of focus include how income levels, age distribution of the population, insurance coverage, and public health initiatives affect healthcare costs. Additionally, the study looks at how psychological and lifestyle factors can lead to increased spending. The findings emphasize the importance of preventive measures, targeted investments in public health, and well-informed policy decisions to tackle the rising costs of healthcare.
