The findings add fodder to a growing movement of self-proclaimed child-free couples who choose not to have children. The number of voluntarily childless women rose from 4.9 percent in 1982 to 6.6 percent in 1995 and dipped to 6.2 percent in 2002, according to the Centers for Disease Control and Prevention. Groups like No Kidding! and ChildFree populate the Internet.

Of course, they have to add the requisite paragraph about how parents are only unhappy because the childfree is not handing over mosubsidizeto subsudize them. Lovely.
