The first cause of death among women in the world are not accidents, cancer, hunger or AIDS, but it's murder. Most often this occurs inside the family. Feminicide is a political term. Talk about feminicide imply looking at the reality, focusing not on the tormentor and his problems, but on the victim, which is always the woman. The term "feminicide" wants to include in one semantic sphere every social practice -physically or psychologically violent- who wants to cancel the integrity, mental and physical development, health, freedom and life of the woman. We can also define the feminicide as a hidden genericide for the impressive number of women demographically missing in the world, which is comparable to a holocaust that is repeated cyclically: in the world dies every four years killed because of their sex a number of women equal to the number of Holocaust victims. Over the past two decades, violence against women is growing exponentially. As proof that even the incredible lack of data and statistics on the phenomenon. Not quantify a phenomenon, not delineate the boundaries and exact dimensions, is to deny it.
