Smoking prevalence in the Americas has dropped substantially in the past decade. Between 2007 and 2015 smoking prevalence decreased from 22.1% to 17.4%, a reduction of 4.7 percentage points, which is more than the global reduction. However, the distribution of smokers by sex in Latin America shows smaller differences than the international ratio of 5.8. As shown in Table 1, this ratio varies widely. In some cases, like Peru, consumption among young men and women is very similar (10.9% and 8.4%), while in others such as Mexico, the percentage of male smokers is three times that of female smokers, and in Ecuador is two and a half times higher.
