INEGI's homicide statistics for 2017 confirm that last year was, to date, the most violent year on record with
31,174 murders. For the last few years, INEGI's numbers have always a bit higher than the government's data (from the National Public Security System of SEGOB), which for 2017 reported 24,893 cases and 28,711 victims. INEGI's data provides
a homicide rate of 25/100,000 inhabitants for 2017, which is also the highest ever recorded. The homicide rate reported by the SNSP (which was 20.5 for 2017, iirc) is calculated on the number of cases rather than victims, so I suppose INEGI's higher rate is more accurate.
The previous high, in 2011 (at the 'peak' of the so-called 'drug war') was 27,213. There have been over 20,000 murders annually since 2010.
INEGI's data can be broken down by several categories, which provides interesting though deeply morbid and disturbing data:
89% of victims were males (27,771), against 3,324 females. This means that the homicide rate for Mexican males only is 46/100,000 males.
