The northern border state of Chihuahua and the southern Pacific coast state of Guerrero both had 77 homicides per 100,000 inhabitants. The institute said in a statement late Monday that there were 26,037 homicides in 2012, in a country whose population is now estimated at 117.3 million. By comparison, Honduras had a 2011 rate of 91.6 per 100,000. Brazil's 2011 rate was about 21.8, according to United Nations estimates.
