Why do people use Facebook?

► We reviewed the literature on the factors contributing to Facebook usage. ► We present a model explaining Facebook usage. ► We concluded that the need to belong and the need for self-presentation are the two primary motivating factors. ► We identified areas for future research. The social networking site, Facebook, has gained an enormous amount of popularity. In this article, we review the literature on the factors contributing to Facebook use. We propose a model suggesting that Facebook use is motivated by two primary needs: (1) the need to belong and (2) the need for self-presentation. Demographic and cultural factors contribute to the need to belong, whereas neuroticism, narcissism, shyness, self-esteem and self-worth contribute to the need for self-presentation. Areas for future research are discussed.
