Taken the Global Impunity Index (IGI 2015) results as a starting point, this work measures impunity at the subnational level in Mexico. Understanding impunity as a multidimensional process that fosters violence, insecurity and corruption, the study measures variation in seventeen indicators for the structure and performance of the justice and public security systems. It also integrates the percentage of unreported crimes as a key variable for understanding impunity in Mexico´s states. It concludes that average impunity in Mexico´s states tend to be very high and that low levels of variation between cases reflects an environment characterized by general and extended conditions of impunity, as was reported in the IGI 2015). The document includes specific data and context analysis for each of the thirty two Mexican states.
