||This paper analyzes the relationship between an individual´s capacity to trust and their overall satisfaction with life in countries of European Union. It concretely focused on four countries selected Denmark, as the most satisfied country in the world, Spain, Czech Republic and Bulgaria as the less satisfied in European Union. Two kinds of trust were examined: general trust referring to interpersonal trust and institutional trust referring to trust in parliament. The trust in people was concluded as more significant for the overall satisfaction of an individual satisfaction than trust in parliament. For example, higher trust in people makes the general public more satisfied. Furthermore, in Denmark and Spain considered to be wealthier countries with higher reported level of satisfaction and trust, the interpersonal trust as well as institutional have less influence on satisfaction than in the average of EU countries.
