For the most recent statistics of 2004 (don't know why that's the most recent), comes this gem for Texas:
In 2004, Hispanic girls ages 15 to 19 accounted for 61 percent of teen births even though only 39 percent of Texas adolescents were Hispanic, according to the federal National Center for Health Statistics.And I have no idea if this accounts for home births by illegal aliens. This State - it is a changin'.
