Self defense is a popular topic and there is a steady stream of inquiries asking about self defense. Aikido provides a nice framework for self defense. Here are some resources to get you started. As a starter please read

At some level most come to the Aikido dojo wanting to learn skills to deal with violence, yet our practice is quite somewhat from "real life" violence. Sure, the techniques we learn are derived from battlefield techniques practiced by the samurai, but its a few centuries removed from our daily lives now (not many of us wear body amour and carry swords around with us).

On the subject of violent crime the statistics of incidents between those known to each other are alarming (80% of homicides, 60% sexual ) and in a home or dwelling(57% homicides, 67% sexual).
According to the Australian Institute of Criminology only 6% of female homicides were perpetrated by a stranger
Over whelmingly the statistics point to common risk factors like young males (both the perp and victim), drugs and alcohol.
