The relationship between healthcare expenditure and economic performance is a topic of significant interest in the field of economics and public health. This study aims to explore the correlation between healthcare spending and overall economic growth, with a focus on the long-term implications for developing and developed countries. By analyzing a comprehensive dataset that includes various economic indicators and healthcare expenditure rates, this research examines how increased healthcare investment correlates with improved economic outcomes. Findings suggest that there is a positive, albeit non-linear, relationship between healthcare expenditure and economic performance, with the potential for significant benefits to national economies. However, the magnitude of the impact varies widely across countries, highlighting the importance of contextual factors such as healthcare systems, economic development levels, and policy frameworks. The study concludes that strategic investment in healthcare can be a catalyst for economic growth, but it must be balanced with considerations of cost-effectiveness and efficiency in resource allocation.
