"But for one out of every four women in this country, home is anything but safe. When she closes her door – reluctantly — to the protection of the outside world, it triggers fear and a growing dread. She’s alone with the enemy — her loved one, the one who is supposed to love her. But instead of kisses and hugs she gets fists and bruises. She cries and withdraws, he cools down and later is remorseful. They reconcile, there’s a honeymoon period and he promises never to hit her again. Then one day, out of nowhere, the vicious cycle of abuse starts all over again in her black-and-blue world: He didn’t like her dinner, or how long she was out shopping or the tone in her voice. It’s a life lived on eggshells, a house of cards that could come crashing down at any moment."

Where do these statistics come from? What is the basis for these numbers? Is the dramatic language really true (1 in 4 are black-and-blue)?

I think not. What are the real data?
