Internet use is unevenly distributed among the population of most developed countries. The literature on the subject offers an abundance of evidence regarding the variety of factors that affect this type of inequality referred to as the Digital Divide. Taking Spain as a case study, our empirical goal in this paper is to put forward a model of analysis to improve our ability to predict the effect of a heterogeneous set of variables on the Digital Divide. This model uses as independent variables the Nationality (Immigrants and Spanish Citizens), gender, age, education level, employment status, size of habitat and regions. Our findings show that the level of education variable has the greatest weight in explaining the Digital Divide in Spain. On this basis, we address our second -theoretical -goal in this paper, namely, to discuss the inequalities brought about by the Digital Divide. To do so, we introduce the concept of third Digital Divide.
