Research Shows Reduction in Crime Rate and Paternity Suits:

Last week the University of Arkansas released another follow-up study on the Milwaukee Parental Choice Program. Since its original study more than a decade ago, researchers have been able to follow up on the original students to measure real-life impacts of the program. Once again, researchers found positive impacts from the voucher program.

From the peer-reviewed study:

We examine the effects of Milwaukee’s school voucher program on adult criminal activity and paternity suits. Using matched student-level data, we find that exposure to the program in eighth or ninth grade predicts lower rates of conviction for criminal activity and lower rates of paternity suits by ages twenty- five to twenty-eight. Specifically, exposure to the MPCP is associated with a reduction of around 53 percent in drug convictions, 86 percent in property damage convictions, and 38 percent in paternity suits.
