The balance of Mexican political science in the beginning of the 21st century is positive. The development of the discipline is reflected in the growing number of undergraduate and graduate programs, publications, professional associations and researchers. However, internal fragmentation still persists. The discipline is not yet seen as a singular science (political science), but rather as a plural one (political sciences). Nevertheless, the country’s democratization was favorable to the discipline in terms of opening a range of issues that now demand scientific explanations, and this has been reflected in the growth of the field of studies. In comparison with prior decades, Mexican political science has grown steadily and the future is promising for its development.
