One possible focus of the study could be to investigate patterns and trends in crime rates across different states or regions in the United States. The sociologist may examine the variations in crime rates, comparing factors such as socioeconomic status, population density, ethnic composition, education levels, and access to resources or social services. By analyzing these variables, the sociologist can attempt to identify potential correlates or determinants of crime within different areas of the country, shedding light on the social, economic, and cultural factors that contribute to criminal behavior.
