How are children affected by divorce?

This is my second quarter at TCC. I am at the beginning of my educational path with a very long term goal in mind. I am majoring in psychology and my eventual goal is to attain my Ph.D. and use my love of children and helping others to make the world a better place. (and world domination). I want to be able to give a voice to all the children that are unable to stand up for themselves. I want to be a child advocate for all those that are living in unhealthy environments. I come from a family with both biological parents in the home. My parents have been married for over thirty years. My husband grew up with both of his parents and they are still married as well. I look around and see that is a rare occurrence. I am curious how the children of divorced parents are affected by their choices. In what ways are children affected by divorce? Is there an age group that is affected more than another?
