Surprisingly little has changed over the past year in terms of cartel dynamics. Various leaders and lieutenants have been arrested or killed, and additional splintering has continued for some already fractured groups, but by and large, 2018 was characterized by a stasis in the conflict zones of the assorted factions. In the past, periods of stasis often entailed that cartel groups were staying within their areas of control and that violence would be lower. However, in the current period, large and bloody struggles are continuing unresolved, and cartel groups remain locked in nasty turf wars. This environment means that most of these clashes will rage on well into 2019. This violence has been reflected in the murder statistics, as the homicide figure for 2018 hit 33,341 — far surpassing the 2017 tally of 29,168.
