A report by the Centers for Disease Control and Prevention is showing a big drop in teen birth rates that some experts say is startling.
All states but West Virginia and North Dakota showed significant drops over five years. But the Mountain States of Arizona, Colorado, Idaho, Nevada and Utah saw rates fall by 30 percent or more.
In 22 states, teen Hispanic birth rates plunged at least 40 percent, which was described as "just amazing," by the report's lead author, Brady Hamilton of the CDC.
Experts believe the explanation is complicated and probably varies a bit from state to state.
The report released Thursday shows the lowest birth rates are in New Hampshire, Massachusetts, Connecticut and Vermont. The highest continue to be in the South, led by Arkansas and Mississippi.
An overall decline in births the past five years is attributed to a weak economy.
