AbstractObjectivesThe question of a declining nonâHispanic white (NHW) population has sparked debate in the United States. In examining this question, three bodies of research have emerged. One group reports that the decline is real, a second argues that it is an illusion, and the third provides evidence that the decline is concentrated within socioâeconomic segments of the NHW population. We use the third groupsâ insight as the starting point for our research objective.MethodsIn conjunction with data from Census Bureau sources, we use a series of Regression Models in this inquiry.ResultsOur results show that the decline of the NHW population is real and related to factors embedded in the institutional anomie theory (IAT) framework.ConclusionsWe conclude that the IAT framework is a suitable approach for examining the question of NHW population decline. However, we suggest that future research consider refining our approach by: (1) using subâstate areas as the units of analyses; (2) examining changes in the NHW population relative to lagged changes in the IAT framework at both the state and subâstate levels; (3) placing our framework into an âalgorithmic modeling approachâ that employs machine learning; and (4) developing anomie predictors.
