Teenage pregancy rates

David Farrar has blogged on Fewer teenage pregnancies, from an article in Stuff TV shows credited with fall in pregnancies which says:

Last year 4247 teenagers gave birth – down 387 from 2010, Statistics New Zealand figures show.

That’s interesting but it’s just a two year movement and doesn’t say anything about trends, so I looked up some numbers.

It has gone down significantly since a surge in the seventies. There has been fluctuation rather than a trend this century, it is going down but it’s been lower in 2002 and 2003.
