In considering simply the subindex measuring human, cultural, and natural resources, Mexico ranks in the 13th place on a worldwide level, 10th for the natural resources criteria and 19th for the cultural criteria.
The TTCI report also notes Mexico's main weaknesses, which includes ground transport infrastructure (ranked 79th), insufficient health and hygiene (ranked 64th) and safety and security concerns (ranked 128th).
