Brazil's main competitive advantages are its natural resources, which ranked 1st on this criteria out of all countries considered, and ranked 23rd for its cultural resources, due to its many World Heritage sites. The TTCI report notes Brazil's main weaknesses: its ground transport infrastructure remains underdeveloped (ranked 116th), with the quality of roads ranking in 105th place; and the country continues to suffer from a lack of price competitiveness (ranked 114th), due in part to high ticket taxes and airport charges, as well as high prices and high taxation. Safety and security have improved significantly: 75th in 2011, up from 128th in 2008.
