Values for predictors vary between synthetic control units for each outcome due to differing weights of each donor municipality. See online supplemental appendix table 1 for more details about each predictor and online supplemental appendix table 2 for more details on the weights for each municipality within each synthetic control unit.
*Because the synthetic control set weights may be different for different outcomes, the characteristics of each synthetic control vary and thus are shown by outcome.
