college students come from higher socio-economic backgrounds than individuals who do not go on to college (Lenk et al., 2012).

These demographics vary dramatically across colleges. According, the representativeness of college samples will vary. Conclusions drawn from college populations should be viewed within the context of that particular sample and the question under investigation.
