From Crisis to Resilience: The Role of Education, Population Dynamics, and Social‐Environmental Policies in Improving Life Expectancy and Sustainable Development

ABSTRACT Human growth aims to improve life expectancy and aligns with Sustainable Development Goal 3, which promotes healthy lives and well‐being for all. The E7 countries (Turkey, Brazil, India, Mexico, Indonesia, Russia, and China) face rapid economic and demographic changes that influence public health, and this study examines the determinants of life expectancy in these nations from 2000 to 2023. The analysis is distinctive because it considers environmental and social factors together, including water availability, urbanization, healthcare expenditure, education, income inequality, sanitation, population density, and greenhouse gas emissions. These indicators capture both natural pressures and social conditions that shape long‐term health outcomes. The study applies the Cross Sectional Augmented Autoregressive Distributed Lag model, which allows estimation of short and long‐run effects while accounting for heterogeneity and shared shocks, supported by robustness checks using AMG, CCEMG, and Fixed Effects with Driscoll–Kraay standard errors. The results show that unsafe water, pollution, and social inequality reduce life expectancy, while higher investment in healthcare, education, and sanitation improves it. By integrating environmental and social dimensions, the study provides a clearer understanding of public health challenges in fast‐growing E7 economies and highlights areas where coordinated policies can strengthen long‐term health outcomes.
