In 2014 Minnesota had 15.5 births per 1,000 female teenagers.
Since 1993 there has been a relatively steady overall decline in births to Minnesota adolescent girls ages 15 to 19, with the current rate at less than half of what it was 20 years ago. However, there are noticeable disparities between racial groups. In 2014, Hispanic, Black, and American Indian teenage girls were more than twice as likely to have a baby compared to all Minnesota teenage girls.
