未成年懷孕
Teenage pregnancy is a girl between the ages of 13 and 19 becoming pregnant. The term used in every day speech usually refers to girls who have not yet reached legal adulthood, which in Australia is anyone under the age of 18. At the national level, the teenage birth rate has declined in the last decade. The rate was about 16 babies per 1,000 women aged 15–19 years between 2011 and 2012 but this had fallen to 11.9 births per 1,000 women aged 15–19 in 2015, the lowest figure on record. Terminations can be performed up until the 12-week mark. About half of all teenage pregnancies are terminated in Australia.
