Résumé : The characteristics of Mexico are different to the characteristics of countries where the mainstream theories on social movements were developed — which are countries with consolidated democracies. Hence, to study the Mexican case, one must be aware of this difference, as one of the fundamental aims of this thesis is to evaluate the pertinence of these theories in a young democracy with an authoritarian heritage that experiences conditions of social inequality, insecurity and low levels of trust in public institutions. A question that must be asked first is whether the case of Mexico, following the mainstream theories, is going to produce similar outcomes to those that we can find in the literature, or due to the peculiarities of this country, the outcomes are going to be different. In this research work we take the individual as a unit of analysis. Thus, we analyze the variables that have an effect on the propensity of individuals to protest. Beyond the paths of pure micro, meso or macro level analyses, this thesis examines these three social levels in combination to explain the individuals' likelihood to participate in protest events. That is to say, we analyze the effects of the macro or meso level on the micro level. With this aim, we seek to determine whether the case of Mexico is going to produce similar outcomes to those that we can find in the literature or, whether due to the peculiarities of this country the outcomes are going to differ. Contrary to other studies which only analyze the characteristics of protesters, in this work we analyze the characteristics of both protesters and non-protesters. The latter is an important group of analysis, since with it we can make a real contrast to observe which variables are more likely to trigger protest participation in individuals.
