The safety and prosperity of a nation are intrinsically linked to the life expectancy of its population, given its role in capturing both the current health status and future prospects of its people. A healthy population is fundamental to national stability, economic development, and social cohesion. As such, identifying the determinants of life expectancy is essential for formulating policies that ensure the long-term security of the nation. This study provides the first empirical evidence of health expenditures’ causal effect on life expectancy in Kazakhstan. The linkage between health expenditures and life expectancy at birth in Kazakhstan is particularly pertinent, given the country's ongoing initiatives to enhance its healthcare infrastructure. With continued investments in health services, it is crucial to evaluate the connection between healthcare spending and life expectancy to determine the effectiveness of these financial commitments. This research utilizes the Toda-Yamamoto (T-Y) Granger causality test and Johansen cointegration analysis to explore the relationship between the variables for the period spanning 2000 to 2021. The results indicate that health expenditures significantly Granger-cause life expectancy, with a chi-square statistic of 9.497 and a p-value of 0.0021, signifying predictive power. Moreover, the Johansen cointegration analysis identifies a long-term equilibrium relationship between the both variables, highlighting the close interdependence between health outcomes and expected lifespan. These findings underscore the necessity for sustained investment in healthcare to enhance life expectancy. Policymakers in Kazakhstan should focus on the strategic allocation of healthcare resources to foster improved long-term health outcomes.
