During the past two decades, internet has penetrated into people’s personal lives, significantly. People communicate with each other through internet facilities such as email services, social web pages, etc. Internet has influenced so much of our lives that many people get addicted and it has become a serious issue among different societies. In this study, we perform an empirical study to find the relationship of three issues of age, gender and employment status on internet addiction behavior. The survey selects 190 men and 160 women from a city of NajafAbad located in province of Esfahan, Iran and a questionnaire consists of 35 questions are distributed among them. The survey uses Chi-Square statistics to examine the effects of three mentioned factors and the results indicate that internet addiction is more among singles than married (Chi-Square=19.94). The survey also indicates that internet addition is more on men than women do (Chi-Square=6.64). However, our survey does not find any evidence to believe job employment has any impact on internet addiction.
