In a large Austin inner-city high school, the student density is low because it's in a low-income neighborhood which many families have moved away from. In another high school, located in a small, middle-class Austin suburb, the high school is terribly over-full (it has a very high density) due to an influx of families moving out of the city. Research shows that the low-density, inner-city school has a significantly higher incidence of truancy, violence, and drop-outs. How would John B. Calhoun's study of density, crowding, and deviancy apply to these differences?
A. It would not apply very well, because this example demonstrates how factors other than density and crowding can explain deviant behavior. B. It would show that even though the inner-city school is less crowded, its density is still creating problematic behaviors. C. It would illustrate how we cannot study crowding and density separately but must always consider both at once. D. It would demonstrate that the effects of crowding and density only occur in low-income areas.
