In the current study, we examined the relationship between perceived person happiness and factors that influence this perception, also, is inferred that life satisfaction is influence by happiness. Among 2494 Spaniards individuals of both sexes, we found that these individuals valued political situation, economic situation and socio-demographic characteristics to have a strong association in that order, with happiness and that this last construct is a fundamental factor to life satisfaction. The importance of perception is validated using a structural equation model that evaluates relationships and validity on the constructs in question. Collinearity statistics, average variance extracted, and an estimated partial least square regression model are evaluated to confirm independent meaning, correct construct measure and endogenous variable explanation by the predictive constructs. Results indicate that the level of happiness in Spaniards is most influenced by political perception. Theoretical and practical implications of these findings are discussed, and it is proposed to continue this study in a non-developed country.
