The Public Policy Institute of California produced a report on the results of Prop 47 in California. According to the report, the measure contributed to lowering recidivism rates and did not lead to a rise in violent crimes. Re-arrest and re-conviction rates dropped by 1.8 percent and 3.1 percent, respectively making Prop 47's intention of reducing incarceration numbers successful.
Of the 12 California counties analyzed in the PPIC report, jail bookings declined by 8 percent a year after the measure passed, with larger declines for whites and Latinos than for African-Americans. The overall decline in jail bookings was driven by fewer bookings for Proposition 47 drug and property offenses.
