This study explores the intersection of two main demographic variables, religion and age, and the ongoing phenomenon of partisan geographical sorting in the United States. Americans have been migrating to areas composed of politically like-minded individuals for the past few decades, resulting in the existence of Republican and Democratic clusters throughout the country. Republicans are sorting into rural areas, while Democrats are sorting into urban areas. Republicans and rural residents as a whole are more religious than are Democrats and urban residents. In addition, on average, Republicans and rural residents are older than Democrats and urban residents. Moreover, religion and age are correlated with each other, as older Americans are, on average, more religious than younger Americans. This research expands upon previous studies by further evaluating the importance of the correlations between religion and age and partisan geographical sorting in the United States
