Kris: yes. Has to do with social organization and epidemiological vectors for disease transmission -- migrant or travelling populations with high fluidity in relationships (such as much of S.A.'s industrial workforce between bantustan and job) with a high marginal population provides different social vectors. The causation link is well established for the HIV=AIDS question and the effects are real.
