According to a new government report, teen births are at their lowest level in nearly 70 years.
The National Center for Health Statistics says the number of teenagers giving birth dropped nine-percent from 2009 to 2010.
There were 34.3 births for every 1,000 teens in 2010.
That's the lowest rate since 1946.
The rates dropped across all racial and ethnic groups, and nearly all states.
Analysts say more teens are using contraception, such as condoms and birth control or just waiting to have sex.
