A Wisconsin lawmaker has proposed legislation that would require the state to officially declare single parenting as child abuse.

Republican Senator Glenn Grothman presented Senate Bill 507 which would require the Child Abuse and Neglect Prevention Board to emphasize that non-marital parenthood is a contributing factor to child abuse and neglect.

The bill would also require educational and public awareness campaigns to emphasize that not being married is abusive and neglectful of children, and to underscore "the role of fathers in the primary prevention of child abuse and neglect."

The U.S. Census Bureau stated that in 2009 there were approximately 13.5 million single parents in the U.S., with single mothers outnumbering single fathers five to one. In the state of Wisconsin, single-parent households make up a third of households.
