No Kidding! International is an international non-profit social club created for singles and couples who have never had children, regardless of the reason. Some of their members are childfree, i.e. they are voluntarily childless. The first chapter of this organization was begun by Jerry Steinberg (the "Founding Non-Father" of NO KIDDING!) in Vancouver, BC, Canada in 1984. There are numerous chapters in Canada, the United States and several other countries.
The stated purpose of No Kidding! is to give childless and childfree adults a place to share common interests which do not involve children, as well as to provide the opportunity to make new childfree friends. Anyone who has never been a parent, regardless of the reason, is permitted to join. The club organises a wide range of activities, including hiking, wine & cheese parties, restaurant dinners, concerts, etc.
The organization has annual conventions where people from all over the U.S. and Canada gather. Conventions were held annually between 2002-2006. So far, conventions have been held in Las Vegas, New Orleans, Seattle, Philadelphia and Toronto. In 2010, the convention was in Houston.
No Kidding!'s chapters, founder and spokespeople have made numerous media appearances, including WB 11 News in New York City, CNN's Anderson Cooper 360, Fox News Chicago, Business Week, CBS News, the Sally Jessy Raphael Show, the Boston Globe, the Chicago Tribune, Salon.com, RAI, Arte, and the Oxygen Network, as well as local newspapers, radio shows and TV programs.
