Explanation:
The quality of life is an index that is calculated by using different estimators that covers diverse aspects of human life such as, among others health, safety, happiness, security, transportation, etc. The INEGI (National Institute of Statistics and Geography, Mexico) calculates the quality of life by using the estimators above described (and others). In my opinion, the most important one of this list is political governance, because it is an underlying characteristic that has a direct effect on the further estimators, thereby affecting their performance in a short/medium-term period.
