In Mexico, criminal legislation is shared between the federal and state governments. The federal law establishes the age of 12 as the minimum age of consent, while the age at which there are no restrictions for consensual sexual activities is 18 (sex with someone 12-18 is not illegal per se, but can still be open to prosecution under certain circumstances). Local state laws may override the federal law. In practice, the decision as to whether or not to prosecute is left to state authorities regardless of the younger person's age. At state level, the minimum ages of consent vary between 12 (and puberty in a few states) and 15, while the age at which there are no restrictions for consensual sexual activities vary from 16 to 18 (most common 18).
