The growth in the sex market post-decriminalization suggests that lower-risk workers are entering the market. Furthermore, indoor sex workers appear to have lower disease rates than outdoor sex workers. Empirical evidence also suggests that risky behaviors, i.e., performing sexual acts without using a condom or other method of protection against disease, fell after decriminalization. These changes in the market structure and composition post-decriminalization could help explain why the rates of STIs fell.
