Two years of significant declines in the number of homicides came to an end in 2015, when the figure rose 2.5%.
The national statistics institute, Inegi, reported that the downward trend seen since the beginning of the administration of President Enrique Peña Nieto was reversed last year when 20,525 homicides were recorded, up from 20,010 the year before.
Homicides decreased by 11.2% in 2013 and by another 13.3% in 2014.
The increase reported by Inegi has been echoed in other official data: the National Public Security System reported an 8.8% increase in homicides last year.
The newspaper Milenio performs its own monthly analysis of murders related to organized crime, and reported they were up 4.8%.
Inegi’s numbers indicate that the homicide rate per 100,000 inhabitants was 16.9 last year, up slightly from 16.7 in 2014.
The state with the largest number of reported homicides was that of México, with 2,671, which translates into 17 per 100,000.
In the state of Guerrero homicides shot up 39% to 2,402, or 67 per 100,000 people.
Homicide rates are also high in the northern states of Chihuahua and Sinaloa, with 42 and 36, respectively.
The upward trend in homicides was evident near the end of 2015 and in response, Interior Secretary Miguel Ángel Osorio Chong said in November that a strategy requiring constitutional reform was needed if security was to be improved in the states with the highest incidence of homicides.
That reform was approved in June and will create a new public security system.
