According to the Corruption Perceptions Index 2018, an index that measures perceived levels of public sector corruption according to experts and business people, Mexico ranked poorly, among the lowest rankings with a rank of 138 (out of 180) and a score of 28 / 100 (where 0 is highly corrupt and 100 reflects no corruption). It is estimated that 1 in 3 persons in Latin America had paid bribes in that same year (Transparency International, 2018).
