Cultures have various compositions, and thus different levels of cultural vitality. There are three major tiers of cultural vitality and a nominal culture that's called Tier I.

  • Tier I: Nominal culture
  • Tier II: Operational culture
  • Tier III: Sustainable culture
  • Tier IV: Gravitative culture

These tiers are differentiated on whether they exhibit six vital signs, each represented by two to four vital indicators.
