Good news here.. but "unwanted" or "unplanned"?

US women of childbearing age who were surveyed in 2002 revealed that 14 percent of their recent births were unwanted at the time of conception, federal researchers said yesterday.
In a similar 1995 survey, only 9 percent were unwanted at the time of conception.

''I don't think there's any mystery here," said Susan Wills, of the US Conference of Catholic Bishops.

The new data underscores that more women are turning away from abortions, even when it's a pregnancy they don't initially want, said Wills, associate director for education in the Conference's Secretariat for Pro-Life Activities.

I wonder what the wording of the survey was? "Unwanted" is such a negative term, whereas "unplanned" might be more appropriate coming from a mother.... I hope.
