Abstract
With an aging population and an increase in health care spending across many nations, there is a need to determine what is affecting this increase and whether this trend can be expected to continue into the future. This paper aims to investigate the possible differences in health care expenditures in different countries. The study incorporates the use and analysis of several independent variables that are believed to affect health care spending in an array of countries including life expectancies, the increase in aging populations, health care spending on private sectors, and the quality of health care as represented by the number of hospital beds available to patients. This paper seeks to determine if there is in fact a steady correlation among these independent variables among all thirty pre-selected countries, or whether health care expenditure varies by country and is affected by other determinants. The results of this study reveal that, as predicted, female life expectancy, spending on private health care sectors, and the increase of population over the age of 65 does in fact positively affect the health care expenditures among countries.
