Individual perception of happiness is somewhat universal (Pflug 2009), however, there are studies indicating that individual, cultural and social factors significantly influence a person’s perception of life satisfaction and happiness, while demographic and socioeconomic status, can influence individual levels of happiness and life satisfaction (Angner 2010, Graham 2008). Moreover, research on happiness has shown that socio-demographic differences (eg, gender, age, race, income, and education) can affect a person's life satisfaction (Kim-Prieto 2005). Every year, life satisfaction and happiness are considered more and more as an important goal at a personal and societal level, and international colleagues put forward arguments in favor of happiness being the ultimate goal, and that all other aspects, such as economic, medical and social policies should be designed in such a way as to increase it. The purpose of this article is to study the relationship between socio-demographic factors and life satisfaction of modern students.
