Sociology students study patterns in interactions, experiences and life outcomes particularly as they relate to group membership. For example, fathers in the United States are more likely to actively participate in day-to-day parenting than they did 50 years ago. In explaining these changes, and in identifying structural changes needed to bring about different social arrangements, sociologists study race, social class and gender. Sociologists also consider culture, social movements, globalization, deviance and crime against communities and their environments. Indeed, sociology seems to offer something for everyone who is anxious to understand the web and rhythm of human behavior.
