This dissertation examines the associations between air pollution, maximum air temperature, and county-level mortality rates due to cardiovascular and respiratory diseases across the United States from 2010 to 2019. Employing Negative Binomial Generalized Linear Models, the study examines the temporal and geographical variations impacting these health outcomes, further augmented by sociodemographic analysis. Initial findings support a positive correlation between PM2.5 air pollution levels and cardiovascular mortality, with regional disparities underscoring a complex interplay of environmental and sociodemographic factors. A focused examination within Texas reveals a nuanced relationship between environmental variables and mortality rates, moderated by regional and sociodemographic contexts. Through a systematic exploration of environmental, sociodemographic, and mortality rates, this study furthers the understanding of environmental health challenges. The dissertation emphasizes the need for localized and region-specific approaches in environmental health research, advancing the emergent field of environmental demography, and laying a groundwork for future investigations into the multifaceted interactions across various regional delineations. Additionally, the identification of nuanced relationships between environmental variables and mortality rates highlights the critical need for continued exploration to effectively address the pressing public health challenges posed by air pollution and temperature variations.
